| Popis: | The interaction of hydrated copper(II) chloride or bromide with phenyl-2-picolyl ketone hydrazone and phenyl-2-picolyl ketone phenyl hydrazone, PPKhy and PPKPhy, respectively, have been studied employing elemental analyses, spectral studies (IR and electronic spectra) and the variable temperature magnetic susceptibility together with the electron spin resonance spectra. The complexes of the formulae [CuLX 2 ] 2 , L = PPKhy or PPKPhy and X = Cl or Br, are found to be dimeric through a halide bridge while those of the stoichiometry [CuL 2 ]X 2 are monomeric in nature. The magnetic data showed that the dimeric complexes possess antiferromagnetic interaction. The mechanism of the magnetic interaction is discussed based on the variable temperature magnetic data and ESR spectra. |
