Bimetallic Perthiocarbonate Complexes of Cobalt: Synthesis, Structure and Bonding.

The syntheses and structural elucidation of bimetallic thiolate complexes of early and late transition metals are described. Thermolysis of the bimetallic hydridoborate species [{Cp*CoPh}{-TePh}{-TeBH-Te,H}{Cp*Co}] (Cp* = -CMe) () in the presence of CS afforded the bimetallic perthiocarbonate complex [(Cp*Co)(-CS-S:S')(-S-S″:S‴)] () and the dithiolene complex [(Cp*Co)(-CS-S,S'] (). Complex contains a four-membered metallaheterocycle (CoS) comprising a perthiocarbonate [CS] unit and a disulfide [S] unit, attached opposite to each other.
