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, all of which have similar structures. 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 salts of nickel(II) and dimethyldithiocarbamate. In terms of structure and bonding the nickel is square planar, and the complex is diamagnetic.

- Iron tris(dimethyldithiocarbamate) - a related compound with three dithiocarbamate ligands coordinated to iron.
