title: Bis(tetraphenylphosphonium) (micro-tetrathiotungstenio-kappa(4)S,S':S":S"')bis[(cyano-kappaC)cuprate](2-) acetonitrile solvate monohydrate.
abstract: The reaction of CuCN and KCN with (NH(4))(2)[WS(4)] followed by cation exchange with PPh(4)Br produced the title compound, (C(24)H(20)P)(2)[Cu(2)WS(4)(CN)(2)].CH(3)CN.H(2)O or (PPh(4))(2)[(NC)Cu(micro-S)(2)W(micro-S)(2)Cu(CN)].MeCN.H(2)O. In the structure of the dianion, [(NC)Cu(micro-S)(2)W(micro-S)(2)Cu(CN)](2-), the WS(4) moiety acts as a bidentate ligand that binds two CuCN groups, thus forming a slightly bent WCu(2) core with approximate D(2d) symmetry. The W-Cu distances are in the range 2.6463 (6)-2.6545 (6) A.
