The coordination chemistry of carbene-CS2 adducts selected NHCs and cAACs their redox active nature in nickel complexes is reported. These azolium-2-dithiocarboxylate ligands can be considered as 1,1-isomeric dithiolene analogues bearing a 2π electron reservoir. Depending on the co-ligands attached to nickel, square planar mono- or bis-(carbene-CS2) types [Ni(IiPr)2(carbene-CS2)] (2a-g) (carbene = cAACMe, IDipp, IMes, BIMe, BIiPr, IiPr, IiPrMe) [Ni(carbene-CS2)2] (3a-c) IMes) are accessible by alkene substitution using [Ni(IiPr)2(ƞ2-C2H4)] [Ni(COD)2] starting material (cAACMe 1-(2,6-di-iso-propylphenyl)-3,3,5,5-tetramethylpyrrolidin-2-ylidene, IR 1,3-diorganylimidazolin-2-ylidene, IRMe 1,3-diorganyl-4,5-dimethylimidazolin-2-ylidene, BIR 1,3-diorganylbenzimidazolin-2-ylidene). In 2a-g 3a-c, all coordinated κ2-S,S' fashion nickel(ii) ligated either formally one reduced two states. 3a-c reveal intense NIR absorptions, which shift upon metallic reduction nickelate salts type [Cat]+[Ni(carbene-CS2)2]˙- (4a-bcat). these nickelates, an additional shared across ligand-centered SOMO π-symmetry delocalized over both results moieties with formal -1.5 charge per ligand, further demonstrating flexible ligands.
