19.  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.

In the title compound, [AgBr(C18H15P)3]·C2H3N·H2O, the coordination of the Ag atom is close to ideal tetra­hedral, with the three Ag—P bond lengths almost equal [2.5441 (10), 2.5523 (9) and 2.5647 (10) ° A] and the Ag—Br bond slightly longer [2.7242 (5) Å]. The coordination tetra­hedron is slightly flattened, the Ag atom is closer to the PPP plane; the P—Ag—P angles are wider than the Br—Ag—P angles. The voids in the crystal structure are filled with ordered acetonitrile solvent mol­ecules.

In the title compound, the silver(I) ions are coordinated by four tri­phenyl­phosphane ligands and two 2,2-di­allyl­malonate anions in a μ4-(κ6 O 1,O 3:O 3:O 1′,O 3′:O 1′) mode, setting up an Ag4O8P4 core.
In the tetra­nuclear mol­ecule of the title compound, [Ag4(C9H10O4)2(C18H15P)4], the AgI ion is coordinated by one P and three O atoms in a considerably distorted tetra­hedral environment. The two 2,2-di­allyl­malonate anions bridge four AgI ions in a μ4-(κ6 O 1,O 3:O 3:O 1′,O 3′:O 1′) mode, setting up an Ag4O8P4 core (point group symmetry -4..) of corner-sharing tetra­hedra. The shortest intra­molecular Ag⋯Ag distance of 3.9510 (3) Å reveals that no direct d 10⋯d 10 inter­actions are present. Four weak intra­molecular C—H⋯O hydrogen bonds are observed in the crystal structure of the title compound, which most likely stabilize the tetra­nuclear silver core.
