Thermal,electrical,and optical properties of synthesized (1 E,2 E)-(4-bromophenyl)(hydroxyimino)acetaldehyde oxime complexes

The (1e,2e)-(4-bromophenyl)(hydroxyimino)acetaldehyde oxime complexes,[ml2],m = co(ii),cu(ii),and ni(ii),were synthesized and characterized by elemental analysis,magnetic susceptibility,ft-ir spectra,and thermal analysis techniques. the optical band gap of this ligand and its complexes were determined by uv-vis spectrophotometer in the wavelength range 300-800 nm. a decrease in the energy band gap of the [col2],[nil2],and [cul2] complexes has been observed compared with lh ligand. temperature-dependent conductivity measurements showed that all samples behave like semiconductor. activation energies calculated from arrhenius plots showed that the conduction occurs via both intramolecular and the intermolecular processes. © 2013 emin karapinar et al.
