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.

Preparation and structure

The compound precipitates as a black solid upon combining aqueous solutions of nickel(II) salts and sodium dimethyldithiocarbamate. In terms of structure and bonding the nickel is square planar, and the complex is diamagnetic.
