SYNTHESIS AND CHARACTERIZATION OF COPPER(II) COMPLEXES OF 1,3,4-OXADIAZOLE THIOUREAS

The complexes of CUII With ligands derived from some 2-amino-5-substit uted-1,3,4-oxadiazoles and benzoyl isothiocyanates have been synthesis ed and characterised by analytical, magnetic, conductance, thermal and ir, electronic and esr spectral data. The ligands (L's) exhibit neutr al, bidentate behaviour bonding to Cu-II through benzoyl oxygen and ke to sulphur. The complexes, with the composition [CuL(OAc)(2)], conform to square-planar geometry. From the esr spectra of the complexes, the bonding parameters characterising the covalency have been calculated. and discussed.
