Synthesis and structures of mono and binuclear nickel(II) thiolate complexes of a dicompartmental pseudo-macrocycle with N(imine)2S2 and N(oxime)2S2 metal-binding sites

► Synthesis of mono and dinuclear nickel(II) thiolate pseudomacrocycle complexes. ► X-ray crystal structures of mono and dinuclear nickel(II) thiolate pseudomacrocycle complexes. ► Cyclic voltammetry showed a quasi-reversible a one-electron oxidation for both mono and binuclear complexes.
