Nickel bis(stilbenedithiolate) or bis(dithiobenzil)nickel is a coordination complex with the formula Ni(S2C2Ph2)2 (where Ph = phenyl). It exists as a black solid that gives green solutions in toluene due to a strong absorption at 855 nm. The complex is a prototype of a large family of bis(dithiolene) complexes or the formula Ni(S2C2R2)2 (R = H, alkyl, aryl). These complexes have attracted much attention as dyes. They are of academic interest because the dithiolenes are noninnocent ligands.[2] The lengths of the C-S and C-C bonds in the backbone, respectively 1.71 and 1.39 Å, are intermediate between double and single bonds.[3]
The complex was prepared originally by treating nickel sulfide with diphenylacetylene.[4] High yielding syntheses involve treating nickel salts with sulfided benzoin. The complex reacts with ligands to form monodithiolene complexes of the type Ni(S2C2Ph2)L2.[5]
