Synthesis, structural characterization, and electrochemical properties of binuclear copper(II) complexes containing tetradentate Schiff base ligand

Two binuclear copper (II) complexes, [Cu2(saloph)2(μ-O)2]·2(DMF)[H2saloph=N,N′-o-phenylenebis(salicylideneaminato)](a) and [Cu2(salen)2(μ-O)2] [H2salen=N,N′-bis(salicylic-deneaminato) ethylene] (b)were synthesized and characterized by X-ray crystallography. Both of them have distorted rectangular pyramidal geometry around Cu(II). The complete series of complexes show bridging phenoxo groups between the copper centers, together with hydroxo-bridges in these complexes. The complexes have also been characterized by elemental analysis, IR, TG-DTA, and electrochemical results.
