Each Pt atom in the dimeric iodide-bridged title compound, [Pt~2~I~4~(C~18~H~15~P)~2~], is tetracoordinated by a triphenylphosphine P and three I atoms in an approximately square-planar geometry. The __trans__ influence of triphenylphosphine is evident from the longer Pt—I bond length.

✦ Synopsis
The title compound, [Ag 2 I 2 (C 18 H 21 P) 4 ], has a dimeric structure located on a twofold rotation axis with each tetrahedral Ag I ion coordinated by two terminal phosphines and bridged by iodide ligands. Although this structural motif has been reported in bromide-and chloride-silver complexes, this is the first reported dimeric iodide-silver complex with monodentate phosphine.
