520 3 |a The molecular structure of dimeric {[S2P(OiPr)2](PPh3)}2 · 2 CHCl3 is built up about a centrosymmetric eight-membered ring that adopts a chair conformation as a result of bidentate bridging dithiophos phate ligands. The silver atom is in a trigonal planar geometry. Relatively close transannular Ag S interactions are noted which, if considered significant, leads to a tridentate dithiophosphate ligand and a distorted tetrahedral geometry for silver. The presence of two PPh3 molecules in the coordination sphere of silver in monomeric Ag[S2P(OiPr)2](PPh3)2 · 3 CHCl3 as well as a bidentate di thiophosphate ligand gives rise to a tetrahedral geometry. Adducts with lower or greater numbers of PPh3 ligands could not be obtained pointing to the inherent stability of the characterised structures.
