In the title complex, [AgBr(C3H6N2OS)(C18H15P)2], the AgI ion is in a distorted tetra­hedral geometry coordinated by two P atoms from two triphenyl­phosphane ligands, one S atom of an acetyl­thio­urea ligand and one bromide ligand. There are intra­molecular N—H...Br and N—H...O hydrogen bonds present. In the crystal, pairs of N—H...S hydrogen bonds involving thio­urea groups form inversion dimers. In addition, moleclues pack to give sixfold phenyl embraces with an inter­molecular P...P distance of 6.4586 (17) Å.

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 μ2-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).
