Abstract
New VO (II), Cr (II), Co (II), Ni (II), Cu (II) and Zn (II) Schiff base complexes
derived from piperonal have been synthesized and characterized by spectroscopic methods,
conductivity, metal analyses and magnetic moment measurements.
The nature of the complexes formed in ethanolic solution was study following the
molar ratio method. From the spectral studies, Octahedral geometry was suggested for all
prepared complexes except Vanadium (IV) and zinc (II) complexes have square pyramidal
and tetrahedral geometry respectively, Structural geometries of these compounds were also
suggested in gas phase by using hyper chem-8 program for the molecular mechanics and
semi-empirical calculations.
The heat of formation and binding energy for the prepared compounds was calculated
by using PM3 and ZINDO/1 methods. The method of PM3 was used for evaluate the
vibration spectra for the imine and starting material as authentic compound.
Preliminary in vitro tests for antibacterial and antifungal activity show that most of
the prepared compounds display good activity to (Staphylococcus aureus), (Escherichia coli)
and (Candida albicans)
Keywords: Schiff base, Piperonal, hyper chem-8, in vitro, Activity.
