Abstract
The synthesis, spectroscopic, magnetic susceptibility, and superoxide dismutase (SOD) activity measurements of the imidazolate‐bridged complexes [(Salgly)Cu‐Im‐Cu(Salgly)]Na, [(Salgly)Cu‐Im‐Ni(Salgly)]Na, and [(Salgly)Cu‐Im‐Zn(Salgly)]Na, where Salgly = salicylideneglycinate, Im = imidazolate ion are described. Related copper(II) mononuclear complexes are also described. A pH‐dependent EPR and UV‐visible study of a 50% aqueous DMSO solution of the binuclear complexes suggest that the complexes are stable in the pH‐range 6.50–10.50. At lower pH, the imidazolate bridge breaks apart with decreasing pH value.
