Abstract: Variable-temperature X-ray structural study of the complex [(Ph3P)2N]2[Pt2Ag4Cl2(C2Ph)8] prepared by the reaction of cis-[PtCl2(AsPh3)2] and [(Ph3P)2N][Ag(C2Ph)2] in 1:2 M ratio, revealed isolated (non-polymerised) [Pt2Ag4Cl2(C CPh)8]2− anions with a pseudo-octahedral arrangement of metal atoms. The Pt atoms (in mutually trans vertices) are each σ-bonded to four alkynyl ligands in a square planar arrangement; these moieties are bridged by four Ag atoms; each silver atom being η2-bonded to two alkynyl groups. Chloride ligands are asymmetrically bridging two opposite Ag–Ag edges. Silver atoms show strong and unusual temperature-dependent disorder.
