A new polymorph of (O-ethyl dithio­carbonato-κ2S,S′)­bis­(tri­phenylphosphine-κP)silver(I)

A new triclinic polymorphic modification of the title compound, [Ag(C3H5OS2)(C18H15P)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...

Zusammenfassung:A new triclinic polymorphic modification of the title compound, [Ag(C3H5OS2)(C18H15P)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) Å, while for the orthorhombic polymorph these distances are 2.686 (4) and 2.601 (4) Å. The Ag—P distances are similar in both structures.
