Synthesis, Semi-Empirical/PM3 studies of the Benzaldehyde [5-(2-hydroxyphenyl)-1,3,4-oxadiazole-2-yl]hydrazone and some Their Transition Metal Complexes

Abstract

A novel derivative of Benzaldehyde [5-(2-hydroxyphenyl)-1,3,4-oxadiazole-2-
yl]hydrazone have been synthesized and reacted with following transition metal salts
(CoCl2.6H2O, NiCl2.6H2O and CuCl2.2H2O). The free ligand and its complexes have
been investigation by atomic absorption, FTIR, UV, magnetic susceptibility, atomic
absorption, continuous variation and molar conductivity. The Semi-Empirical (PM3)
method was used to calculate the electric energies, binding energy, heat of formation,
band length, theoretical IR and UV spectra.
The calculated theoretical values were in good agreement with the
experimental measured values.
