Abstract

Abstract: Twelve quasi-aromatic metal (Ⅱ) complexes were synthesized from the AEH (APH) and imidazole(benzimidazole)ligands and metal ions. X-photoelectron spectrometric study of these complexes disclosed that due to coordination the 2p bonding energies of the metal ions (M_2p) are decreased and the B. E. of N_1s is increased. During complexation, the direction of electron transfer is from the ligand to the metal ion (L→M); the coordination bonds formed are ofσ-type in character.

Key words: Schiff base, Quasi-aromatic imidazole metal complexes, X-photoelectron spectroscopy
