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 square planar bis(dialkhyldithiocarbamate)s of nickel(II), which feature diverse organic substituents. Nickel bis(dimethyldithiocarbamate) has been marketed as a fungicide, and related complexes are used as stabilizers in polymers. [2]

Preparation and structure

The compound precipitates as a light green solid upon combining aqueous solutions of nickel(II) salts and sodium dimethyldithiocarbamate. [1] In terms of structure and bonding, the nickel is square planar, and the complex is diamagnetic. [3] The structure of the closely related nickel bis(diethyldithiocarbamate) has been determined by X-ray crystallography. [4]

Oxidation of nickel bis(dieethyldithiocarbamate) gives the red-brown nickel(IV) complex [Ni(S2CNEt2)3]+. [1]
