Abstract

In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each Ag(I) ion displays a distorted tetra-hedral coordination geometry with two P atoms from two bis-(di-phenyl-phosphan-yl)methane (dppm) ligands, one bridging chloride ion, one terminal chloride ion and one terminal S atom from the N,N'-phenyl-thio-urea (ptu) ligand. The dppm ligands and the bridging chloride ion force the two Ag atoms into close proximity, with a short Ag⋯Ag separation of 3.2064 (2) Å. In the crystal, complex mol-ecules are linked by N-H⋯Cl hydrogen bonds forming a dimer. The dimers are linked via weak C- H⋯Cl hydrogen bonds forming a two-dimensional supra-molecular architecture in the yz plane. In addition, an intra-molecular N-H⋯Cl hydrogen bond is observed.
