Abstract

The dinuclear title complex, [Ag2(C6H7N2S)2(C18H15P)2], comprises two inversion-related [Ag(C6H7N2S)(C18H15P)] units. The pyrimidinethiolate anion acts both as a bridging and a chelating ligand. The AgI ions are linked via two μ 2-S donor atoms, which generate a strictly planar Ag2S2 core with an Ag⋯Ag separation of 2.9569 (4) Å. The AgI ion presents a distorted tetrahedral coordination geometry. In the crystal, weak C—H⋯N and C—H⋯S hydrogen bonds link the complex molecules into a two-dimensional network parallel to (010).
