Nickel bis(dimethyldithiocarbamate)

Nickel bis(dimethyldithiocarbamate) is the coordination complex on nickel and dimethyldithiocarbamate, with the formula Ni(S₂CNMe₂)₂ (Me = methyl). It is the prototype for a large number of bis(dialkhyldithiocarbamate)s of nickel(II), which feature diverse organic substituents, most of which have feature square planar molecular geometry. Nickel bis(dimethyldithiocarbamate) has been marketed as a fungicide and related complexes are used as stabilizers in polymers.^[1]
