The synthesis, characterization, and chemical properties of Mo(VI)o2(5-X-SSP) and Mo(VI)o2(5-X-SSE), (5-X- SSP2- = 2-((5-X-salicylidene)amino)benzenethiolate; 5-X- SSE2- = 2-((5-X-salicylidene)amino)ethanethiolate; X = Br, Cl, H, CH3O), which contain tridentate (ONS) Schiff base ligands is described. The chemical properties of these molybdenum complexes are compared with those which possess tridentate (ONO) Schiff base ligands. Cyclic voltammetry was used to obtain cathodic reduction potentials (EPC) for the quasi-reversible reduction of the cis-dioxomolybdenum (VI) complexes. Although the reductions are quasi-reversible, trends are observed in EPC both within series and when different series are …
