Abstract

In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each AgI ion displays a distorted tetrahedral coordination geometry with two P atoms from two bis(diphenylphosphanyl)methane (dppm) ligands, one bridging chloride ion, one terminal chloride ion and one terminal S atom from the N,N′-phenylthiourea (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 molecules 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 supramolecular architecture in the yz plane. In addition, an intramolecular N—H⋯Cl hydrogen bond is observed.

Silver(I) complexes containing phosphine and sulfur co-donor ligands have been studied in recent years (Zhang et al, 2003; Wattanakanjana et al, 2013) because of their various applications such as antimicrobial activities (Isab et al, 2010; Nawaz et al, 2011)
