| Abstract: | Carbon disulfide is cleaved by n-propyldiphenylphosphine and nickel(II) bromide in a one-step process, to form two unprecedented complexes: orange, Ni(S2C2(PnPrPh2)2)Br(PnPrPh2)]Br⋅CS2 ( 1 ) and purple Ni{η2-SC(PnPrPh2)2}Br(PnPrPh2)]Br⋅0.5CS2 ( 2 ). Orange ( 1 ) contains a dithiolene-related ligand that results from carbon–carbon bond formation, while purple ( 2 ) contains a remarkable ligand in which two n-propyldiphenylphosphine molecules have added to a carbon atom of a CS unit that is coordinated to nickel. |
