Seven bis-NiII complexes of a N2S donor set ligand have been synthesized and examined for their ability to stabilize Ni0, NiI, NiII and NiIII oxidationstates. Compounds 1–5 consist of modifications of the pyridine ring of the tridentate Schiff base ligand, 2-pyridyl-N-(2′-methylthiophenyl)methyleneimine (XL1), where X = 6-H, 6-Me, 6-p-ClPh, 6-Br, 5-Br; compound 6 is the reduced amine form (L2); compound
