A new triclinic polymorphic modification of the title compound, [Ag(C3H5OS2)(C18 H15P)2], has been found and compared with the previously known orthorhombic modification [Tiekink (1988). Coord. Chem. 17, 239-243]. The two polymorphs have the same molecular shape, viz. a distorted tetrahedral geometry, with a chelating dithiocarbonate (xanthate) and two PPh3 ligands bonded to the Ag atom. However, in this new polymorph, the xanthate ligand is bonded asymmetrically to the Ag atom, with Ag-S distances of 2.5489 (6) and 2.8055 (7) A, while for the orthorhombic polymorph these distances are 2.686 (4) and 2.601 (4) A The Ag-P distances are similar in both structures.
