Crystal structure of bis[(acetato-κO)(imidazolidine-2-thione-κS)bis(triphenylphosphane-κP)silver(I)] di-μ-imidazolidine-2-thione-κ4S:S-bis[(imidazolidine-2-thione-κS)bis(triphenylphosphane-κP)silver(I)] diacetate acetonitrile disolvate tetrahydrate

Abstract

In the title compound, [Ag2(C3H6N2S)4(C18H15P)2](C2H3O2)2·[Ag(C2H3O2)(C3H6N2S)(C18H15P)2]2·2C2H3N·4H2O, the AgI ion in the mononuclear neutral complex exhibits a distorted tetrahedral environment with coordination by two P atoms from triphenylphosphane (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 AgI ions bridged by two S atoms from etu ligands forming a four-membered Ag–S–Ag–S ring. Each AgI 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 tetrahedral environment. In the crystal, the mononuclear complex is linked to lattice water molecules through O—H...O and N—H...O hydrogen bonds, forming a chain along [100]. In addition, the binuclear complex molecules are connected to acetate anions and lattice water molecules via O—H...O, N—H...O and O—H...S hydrogen bonds, also along [100].
