Notes. Synthesis and characterization of several mononuclear cobalt(IV) dithiocarbamates, [Co(S2CNRR′)3]ClO4[R = R′= Me, Et, or CH2Ph; R = Me, R′= Ph; R,R′=–(CH2)4–]

Abstract

Several mononuclear tris(dithiocarbamato)cobalt(IV) perchlorates, [Co(S₂CNRR′)₃]ClO₄[R = R′= Me, Et, or CH₂Ph; R = Me, R′= Ph; and R,R′=–(CH₂)₄–] have been prepared by the chemical oxidation of molecular [Co(S₂CNRR′)₃] with Fe(ClO₄)₃ and characterized. Their visible and i.r. spectroscopic properties are very similar to those of [Co(S₂CNRR′)₃] and the dinuclear Co^III compounds, [Co₂(S₂CNRR′)₅] BF₄. They are d⁵ low-spin complexes and electrochemical measurements indicate that they are stable 1:1 electrolytes in acetone solution.
