Through a diffusion reaction, cuprous bromide, triphenyl­phosphane and 1,3-bis­(pyridin-4-yl)propane (bpp) were self-assembled to form the one-dimensional title compound, [Cu2Br2(C13H14N2)(C18H15P)2]n. Each CuI atom is coordinated by two Br atoms, one P atom from a triphenyl­phosphane ligand and one N atom from a bpp mol­ecule in a distorted tetra­hedral geometry. Two μ2-Br bridges connect two [Cu(PPh3)]+ units to form neutral [CuBr(PPh3)]2 dimers, which are linked by the flexible bridging bpp ligands to form a one-dimensional chain structure parallel to the c axis. The dihedral angle between the pyridine rings of the bpp ligand is 34.59 (14)°.

9.  Crystal structure of di-μ-iodido-bis­[(dimethyl sulfoxide-κO)(tri­phenyl­phosphane-κP)copper(I)] 
The basic building unit of the title complex, CuI(DMSO)(PPh3), reproduced by a symmetry centre, leads to the rhomboid dimers in which the CuI atoms are in a tetra­hedral geometry. The dimers are discrete mol­ecules, but through weak inter­molecular C—H⋯O inter­actions involving two adjacent DMSO ligands, a one-dimensional chain assembly is formed.
The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated CuI atoms are bridged by two μ2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu⋯Cu contact of 2.9874 (8) Å is longer than the sum of the van der Waals radii of two Cu atoms (2.8 Å), excluding a significant cupriophilic inter­action in the actual dimer. C—H⋯O and C—H⋯I hydrogen bonding interactions as well as C—H⋯π(aryl) interactions stabilize the three-dimensional supramolecular network.

The dinuclear title compound, [Ag2(C14H22N4O2)(C18H15P)2(H2O)2](NO3)2, lies across an inversion center and consists of two [Ag(H2O)(PPh3)] units bridged by a bis­(cyclo­hexa­none)oxalydihydrazone ligand. The charge-balance is supplied by two nitrate anions. The symmetry-unique AgI ion is in a distorted tetra­hedral geometry coordinated by a P atom from a tri­phenyl­phosphane ligand, an O atom from a water mol­ecule and a bis­(cyclo­hexa­none)oxalydihydrazone ligand bidentate chelating through the O atom and one of N atoms. In the crystal, O—H⋯O and N—H⋯O hydrogen bonds link the components, forming chains along the b-axis direction. These chains are connected through weak C—H⋯O hydrogen bonds, leading to the formation of a two-dimensional supra­molecular network parallel to (001).

12.  Tetra­kis(triphenyl­phosphane-κP)silver(I) tetra­fluorido­borate 
The title complex, [Ag(C18H15P)4]BF4, was prepared by the reaction of silver(I) tetra­fluorido­borate and triphenyl­phosphane in the presence of 1,2-bis­(pyridin-2-yl)ethyl­ene. The AgI atom is tetra­hedrally coordinated by four P atoms from triphenyl­phosphane (PPh3) ligands. Due to symmetry, the tetra­fluorido­borate anion is disordered over three positions (each with one third occupancy). The tetra­fluorido­borate anion does not coordinate to the AgI atom.

An intra­molecular N—H⋯N hydrogen bond [graph-set motif S(5)] stabilizes the thio­semicarbazide ligand in its anti conformation, and an intra­molecular N—H⋯Cl hydrogen bond between the hydrazine N—H group and the chloride anion influences the arrangement and orientation of the ligands around the metal center. A weak intra­molecular C—H⋯Cl hydrogen bond is also present. In the crystal, complex mol­ecules are connected through N—H⋯Cl hydrogen bonds originating from the amide –NH2 group, and through O—H⋯S and O—H⋯Cl hydrogen bonds involving the solvent water mol­ecule.

25.  Di-μ-iodido-bis­{[(R)-(+)-2,2′-bis­(di­phenyl­phosphan­yl)-1,1′-binaphthyl-κ2 P,P′]copper(I)} 0.67-hydrate 
The structure of the title compound, [Cu2I2(C44H32P2)2]·0.67H2O, has been determined because of its inter­esting catalytic and optical features. The mol­ecule, which has non-crystallographic C2-symmetry, consists of a core structure of two CuI ions, bridged by two iodide ions. Each CuI ion is also coordinated by one equivalent of the chiral bidentate (R)-BINAP ligand [BINAP = 2,2′-bis­(diphenyl­phosphan­yl)-1,1′-binaphth­yl]. Thus, both cations show a distorted tetra­hedral geometry being surrounded by two I atoms and two P atoms from the (R)-BINAP ligands. The complex consists of isolated butterfly-shaped mol­ecules featuring an angle of 146.11 (2)° between adjacent CuI2 planes. The structure displays intra­molecular C—H⋯I hydrogen bonding and contains disordered water. The absolute configuration of this chiral complex was determined by anomalous dispersion effects.
