1.  [1,1′-Bis(diphenyl­phosphan­yl)ferrocene-κ2 P,P′](η5-cyclo­penta­dien­yl)(dicyanamido-κN)ruthenium(II) dichloro­methane monosolvate 
The title compound, [FeRu(C5H5)(C2N3)(C17H14P)2], was obtained by reaction of Cp(dppf)RuCl [dppf = 1,1′-bis­(diphenyl­phosphan­yl)ferrocene] with sodium dicyanamide in dichloro­methane. The RuII atom is capped by an η5-cyclo­penta­dienyl (Cp) ring, a chelating dppf and a terminal C2N3 unit, giving three-legged piano-stool geometry. The C—N—C angle of the N(CN)2 ligand [120.8 (6)°] is significantly smaller than that in the corresponding diruthenium complex [127.2 (9)°; Zhang et al. (2003 ▶). Inorg. Chem. 42, 633–640] due to steric hindrance between the two {Cp(PPh3)2Ru} building blocks. Disorder was found in the dichloro­methane solvent mol­ecule, which was refined as disordered over two positions, with a site-occupancy ratio of 0.53:0.47 (2).

3.  Bis{[μ-bis­(diphenyl­phosphan­yl)methane-1:2κ2 P:P′]nona­carbonyl-1κ3 C,2κ3 C,3κ3 C-[(4-methyl­sulfanylphen­yl)diphenyl­phosphane-3κP]-triangulo-triruthen­ium(0)} dichloro­methane monosolvate 
The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru3(C25H22P2)(C19H17PS)(CO)9]·CH2Cl2, contains one triangulo-triruthenium complex mol­ecule and one half-mol­ecule of the dichloro­methane solvent. The dichloro­methane solvent mol­ecule lies across a crystallographic inversion center leading to the mol­ecule being disordered over two positions of equal occupancy. The bis­(diphenyl­phosphan­yl)methane ligand bridges an Ru—Ru bond and the monodentate phosphane ligand bonds to the third Ru atom. All phosphane ligands are equatorial with respect to the Ru3 triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three phosphane-substituted benzene rings make dihedral angles of 87.18 (11), 59.59 (10) and 89.28 (11)° with each other. The dihedral angles between the two benzene rings are 78.48 (11) and 87.58 (11)° for the two diphenyl­phosphanyl groups. In the crystal, the mol­ecules are stacked along the a axis. Weak inter­molecular C—H⋯π inter­actions stabilize the crystal structure.

7.  (R,R Fc,S Ru)-Chlorido(η6-p-cymene){1-[1-(diphenyl­phosphanyl)ethyl]-2-[2-(diphenyl­phosphanyl)phenyl]ferrocene-κ2 P,P′}ruthenium(II) hexa­fluorido­phosphate 
The asymmetric unit of the title compound, [FeRuCl(C5H5)(C10H14)(C37H31P2)]PF6, contains two independent, geometrically similar RuII complexes of a chiral ferrocenyldiphosphane with piano-stool coordination through the η6-bound p-cymene ligand, two chelating phospho­rus donor atoms, and an exo-oriented chloride ion. The mean bond lengths of the two Ru complexes are Ru—C = 2.276 Å, Ru—P = 2.3816 Å, and Ru—Cl = 2.3924 Å. Both chloride ligands form only intra­molecular C—H⋯Cl inter­actions. Seven weak inter­molecular C—H⋯F inter­actions involving mainly arene H atoms consolidate the crystal packing, which reveals an approximate c/2 pseudo-translation relating the two independent Ru complex mol­ecules.

In the dimeric title compound, [Pd2Cl4{P(C8H9)3}2]·CH2Cl2, the metal complex molecule is situated about an inversion centre and is accompanied by a dichloro­methane solvent mol­ecule situated on a twofold rotation axis. The PdII atom has a slightly distorted square-planar coordination sphere. The effective cone angle for the tris­(3,5-dimethyl­phen­yl)phos­phane ligand was calculated to be 169°. In the crystal, the metal complex and solvent mol­ecules are linked via C—H⋯Cl inter­actions, generating chains along [10-2].

10.  Di-μ-chlorido-bis­({8-[bis­(naphthalen-1-yl)phosphan­yl]naphthalen-1-yl-κ2 C 1,P}palladium(II)) dichloro­methane disolvate 
The title compound, [Pd2{P(C10H7)2(C10H6)}2Cl2]·2CH2Cl2, shows cyclo­metalation of one naphthalen-1-yl substituent of each of the phosphane ligands to the Pd dimer in a trans orientation; the complete dimer is generated by a centre of inversion. Two dichloro­methane solvent mol­ecules create C—H⋯Cl inter­actions with the metal complex, generating supermolecular layers in the ab plane. Additional C—H⋯π and π–π [centroid–centroid distances = 3.713 (3), 3.850 (4) and 3.926 (3) Å] inter­actions join these planes into a three-dimensional supermolecular network.

12.  Chlorido(η6-N 2-diphenylphosphanyl-N 1,N 1-diisopropyl-4-methoxybenz­amidine-κP)(triphenylphosphane-κP)ruthenium(II) trifluoromethansulfonate acetone disolvate 
In the title compound, [RuCl(C18H15P)(C26H31N2OP)](CF3O3S)·2C3H6O, the RuII ion is coordinated in a three-legged piano stool, half-sandwich-type geometry by a chlorido ligand, a tri­phenyl­phosphine and a tethered η6-(phenyl-p-O-meth­oxy) κ1-P N-di­phenyl­phosphino N′-diisopropyl amidine ligand charge-balanced by a trifluormethansulfonate counter-anion. The η6-coordination mode of the arene incorporated into the structure was generated in situ after addition of methyl tri­fluoro­methane­sulfonate to the neutral η5-arene tethered precursor complex [RuCl(PPh3)(η5:κ1-OC6H4C(NiPr2)=N-PPh2)] in di­chloro­methane solution.

13.  Bis[dicyclo­hexyl­(phenyl)­phosphane-κP]silver(I) perchlorate dichloro­methane monosolvate 
In the title compound, [Ag{P(C6H11)2(C6H5)}2]ClO4·CH2Cl2, the AgI atom in the mononuclear complex cation is coordinated by two P atoms of the phosphane ligands [Ag—P = 2.3993 (4) and 2.4011 (4) Å; P—Ag—P = 177.473 (18)°] and the perchlorate anion acts as the counter-anion. There is an Ag⋯Operchlorate inter­action of 2.873 (2) Å, which contributes to the slightly non-linear bond angle about the AgI atom. Weak inter­molecular C—H⋯O hydrogen-bonding inter­actions involving phenyl, cyclo­hexyl and dichloro­methane H-atom donors and perchlorate O-atom acceptors contribute to the stabilization of the crystal structure.

15.  Dichlorido[1-(2-methyl­benz­yl)-3-(η6-2,4,6-trimethyl­benz­yl)-1H-2,3-dihydro­benzimidazol-2-yl­idene]ruthenium(II) dichloro­methane solvate 
The title complex, [RuCl2(C25H26N2)]·CH2Cl2, is best thought of as containing an octa­hedrally coordinated Ru center with the arene occupying three sites. Two Ru—Cl bonds and one Ru–carbene bond complete the distorted octa­hedron. The carbene portion of the ligand is a benzimidazole ring. This ring is connected to the C6H2(CH3)3 arene group by a CH2 bridge. This leads to a system with very little apparent strain. A dichloro­methane solvent mol­ecule completes the crystal structure. Further stabilization is accomplished via C—H⋯N and C—H⋯Cl interactions.

16.  Bis(1-{bis­[2-(diphenyl­phosphino­yl)eth­yl]phosphan­yl}-2-(diphenyl­phosphan­yl)ethane)dinitratoplatinum(II) methanol tetra­solvate 
In the title compound, [Pt(NO3)2(C42H42O2P4)2]·4CH3OH, the Pt atom positioned on a crystallographic centre of inversion. The two symmetry-equivalent nitrate anions are weakly coordinated to the PtII ion, creating, together with four P ligand atoms, a distorted octa­hedral coordination environment.

In the title compound, [RuCl2(C6H14N2)(C28H28P2)]·CH2Cl2, the RuII ion is coordinated in a slightly distorted octa­hedral environment, formed by two cis-oriented chloride ligands, two cis P atoms of a 1,4-bis­(diphenyl­phosphan­yl)butane ligand and two cis-chelating N atoms of a bidentate cyclo­hexane-1,2-diamine ligand. In the crystal, pairs of mol­ecules form inversion dimers via N—H⋯Cl hydrogen bonds. In addition, intra­molecular N—H⋯Cl and weak C—H⋯Cl, C—H⋯N, N—H⋯π and C—H⋯π hydrogen bonds are observed. One of the Cl atoms of the solvent mol­ecule is disordered over two sites with refined occupancies of 0.62 (1) and 0.38 (1).

The PdC3P and PdC2P2 five-membered metallacycles adopt envelope and twist conformations, respectively. In the crystal, inter­molecular C—H⋯O hydrogen bonds link cations and anions into a three-dimensional network. The dichloro­methane solvent mol­ecule is disordered over three orientations with a site-occupancy ratio of 0.5/0.3/0.2. The n-hexane solvent mol­ecule has a crystallographically imposed centre of symmetry.

In the title compound, [Pd(C7H7O2S)Cl(C44H32P2)]·3CH2Cl2·H2O, the geometry around the metal atom is distorted square planar, with a twist angle between the P—Pd—P and S—Pd—Cl planes of 28.11 (2)°. The two Pd—P bond lengths differ by about 0.04 Å and the biphosphane bite angle is slightly obtuse [92.92 (2)°]. There are three dichloro­methane and one water mol­ecule co-crystallized with the palladium mol­ecule, all with atoms in general positions. Alternating water and palladium mol­ecules form four-membered cyclic units through O—H⋯Cl and O—H⋯O hydrogen bonding. One of the dichloromethane solvent molecules is disordered over two positions in a 0.55:0.45 ratio.

20.  Chlorido[2,3,5,6-tetra­kis­(tert-butyl­sulfanylmeth­yl)phenyl-κ3 S 2,C 1,S 6]palladium(II) dichloro­methane monosolvate 
The title compound, [Pd(C26H45S4)Cl]·CH2Cl2, crystallizes with a disordered dichloro­methane solvent mol­ecule [occupancy ratio = 0.67 (4):0.33 (4)]. Two of the tert-butyl groups are also disordered [occupancy ratios = 0.70 (5):0.30 (5) and 0.63 (4):0.37 (4)]. Although the pincer ligand offers the possibility for coordination of two different metal atoms, the present structure shows only the coordination of a single PdII atom in a typical S—C—S tridentate pincer manner. The PdII atom is in a slightly distorted square-planar environment with the two tert-butyl­sulfanyl groups arranged in a trans con­formation and with a chloride ligand trans to the σ-bonded aromatic C atom. The structure exhibits a durene-like ligand frame, forming a dihedral angle of 13.6 (4)° with the metal coordination (Pd/S/S/Cl/C) environment. It is noteworthy that the tert-butyl groups are found in a syn arrangement, this being different to that found previously by Loeb, Shimizu & Wisner [(1998). Organometallics, 17, 2324–2327].

The crystal structure of the title compound, [PtCl2(C25H22NPS)]·0.5CH2Cl2, was determined to establish the coordination properties of the (phosphan­yl)benzyl­idene–methanamine ligand to platinum. In the unit cell two mol­ecules of cis-[PtCl2(C25H22NPS)] are accompanied by a dichloro­methane solvent mol­ecule. The square-planar Pt2+ coordination sphere is slightly distorted with the bidentate ligand coordinated via the P and the amine N atoms, and the Cl atoms located cis at the two remaining coordination sites. Parts of the thiophene ring and the solvate molecule were modeled as disordered with occupancy ratios of 0.55 (2):0.45 (2) and 0.302 (10):0.198 (10), respectively. Weak C—H⋯Cl inter­actions stabilize the crystal packing.
