A new series of copper(II) complexes of the stoichiometry [L2Cu]·nH2O and [(HL)2 CuCl2]·2H2O, where HL is 1-acetylferrocene-benzoylhydrazone, 1-acetylferrocene-4-chlorobenzoylhydrazone, 1-acetylferrocene-4-hydroxy-benzoylhydrazone or 1-acetylferrocene-4-methylbenzoylhydrazone, HL1, HL2, HL3 or HL4, respectively, were synthesized and characterized. IR data showed that all ligands act as monobasic or neutral bidentates coordinated to copper ion via the oxygen and azomethine N atoms. ESR spectra and magnetic data showed that [(L1)2Cu]·H2O and [(L3)2Cu]·2H2O are polymeric exhibiting magnetic exchange interaction. ESR data also indicate that all complexes are associated with a dx2-y2 ground state. The electrochemical behavior of the free ligands and their copper(II) complexes were studied and are discussed.
