Crystal structure of bis-[(acetato-?O)(imidazolidine-2-thione-?S)bis-(tri-phenyl-phosphane-?P)silver(I)] di-?-imidazol-idine-2-thione-?(4) S:S-bis-[(imidazol-id-ine-2-thione-?S)bis-(tri-phenyl-phosphane-?P)silver(I)] di-acetate aceto-nitrile disolvate tetra-hydrate.

ABSTRACT: In the title compound, [Ag2(C3H6N2S)4(C18H15P)2](C2H3O2)2·[Ag(C2H3O2)(C3H6N2S)(C18H15P)2]2·2C2H3N·4H2O, the Ag(I) ion in the mononuclear neutral complex exhibits a distorted tetra-hedral environment with coordination by two P atoms from tri-phenyl-phosphane (PPh3) ligands, one S atom of an imidazolidine-2-thione (etu) ligand and one O atom of an acetate anion. The binuclear cationic complex comprises two inversion-related [Ag(C3H6N2S)2(C18H15P)] units with Ag(I) ions bridged by two S atoms from etu ligands forming a four-membered Ag-S-Ag-S ring. Each Ag(I) ion is coordinated by a P atom of a PPh3 ligand, two S atoms of bridging etu ligands and the terminal S atom of an etu ligand in a distorted tetra-hedral environment. In the crystal, the mononuclear complex is linked to lattice water mol-ecules through O-H?O and N-H?O hydrogen bonds, forming a chain along [100]. In addition, the binuclear complex mol-ecules are connected to acetate anions and lattice water mol-ecules via O-H?O, N-H?O and O-H?S hydrogen bonds, also along [100].
