Preparation Organometallic Compounds Containing Schiff Bases and Study their Electrical Properties

Abstract

The research includes preparation ligand from Schiff bases (DMAB) [2,3 - Dimethyl -1-phenyl-4-(benzledene)-3-pyrozoline-5–one] derived from condensation reaction of 4-aminoantipyrene with benzaldehyde . Complexes of ligand with Fe(III) as symbol (M1) and Cr(III) as symbol (M2) , were prepared. The identity of prepared ligand has been characterized by spectral methods, infrared ray (IR) and measured melting point (m.p.) . A study of molar conductivity of prepared complex solutions in absolute ethanol solvent at a concentration (1 × 10-3M) and laboratory temperature, the complexity increased the conductivity significantly. The corrosion rate for ligand and some complexes were measured by polarization curves resulting from readings of Tafel device by using tap water , and calculation the potential and corrosion current , the ligand has a small corrosion current, while the complexity increased of the corrosion current , and compare the results with similar compounds.
