Five-coordinate complexes, [Ni(S2COR)(TRIPHOS)]X (R = cyclo-C6H11, X = Cl, PF6, [Ni(S2COC6H11)3]; R = Et, X = PF6. [Ni(S2COEt)3]), have been obtained by the reaction of O-alkyldithiocarbonato complexes. [Ni(S2COR)2], with bis(2-diphenylphosphinoethyl)phenylphosphine (TRIPHOS). The structure of [Ni(S2COC6H11) (TRIPHOS)][Ni(S2COC6H11)3] was determined by X-ray crystallography. The compound contains a five-coordinate cation and a hexa-coordinate anion. The geometry about the nickel atom in the [Ni(S2COC6H11)(TRIPHOS)]+ is distorted trigonal bipyramidal with the axial positions occupied by one sulfur atom of the bidentate O-cyclohexyldithiocarbonate and the central phosphorus atom of the TRIPHOS. In the [Ni(S2COC6H11)3] anion, the nickel atom is bonded to six sulfur atoms of three O-cyclohexyldithiocarbonate ligands. Formation of the dithiocarbonato complexes in the reactions of [Ni(S2COEt)2] with TRIPHOS has also been observed.
