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

摘要

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 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 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 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].
