Abstract: The dinuclear title complex, [Ag2Cl2(CH5N3S)2(C18H15P)2], lies across an inversion center. The AgI ion exhibits a slightly distorted tetrahedral coordination geometry formed by a P atom from a triphenylphosphane ligand, two metal-bridging S atoms from thiosemicabazide ligands and one chloride ion. The S atoms bridge two symmetry-related AgI ions, forming a strictly planar Ag2S2 core with an Ag...Ag separation of 2.7802 (7) Å. There is an intramolecular N-H...Cl hydrogen bond. In the crystal, N-H...Cl and N-H...S hydrogen bonds link complex molecules, forming layers parallel to (001). These layers are connected through [pi]-[pi] stacking interactions [centroid-centroid distance = 3.665 (2) Å], leading to the formation of a three-dimensional network.
