Abstract

Anew Schiff base ligand. (HMPHM) 3-((4-chlorobenzylidene)amino)-4-((€-(3-hydroxy-5-(hydroxyl methyl)-2-Methyl)puridin-4-yl)methylene)amino)phenyl)(phenyl)methanon has been Prepared from reacting(3-amino-4-(((3-hydroxy-5-(hydroxylmethyl)-2-methylpyridin-4-yl)methylene)amino)phenyl)(phenyl)methanone with P-Chloro benzaldehyde Co(II), Ni(II), Cu(II), Zn(II), Cd(II), and Au(III) ions were used to create a new series of chelate complexes. The structures of the new Schiff base ligand and their transition metal complexes were characterized by using Fourier-transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (¹H-NMR) technique, ultraviolet visible spectroscopy (UV-Vis), mass analysis, molar conductance, and magnetic susceptibility. [(M)(L)₂] where M = Co(II), Ni(II), Cu(II), Zn(II), and Cd(II), and [(M)(L)Cl]Cl where M = Au (III). The coordination sites of the Schiff base ligand were revealed by FTIR to be through oxygen of the hydroxyl group, and the nitrogen of azomethine groups. Based on data obtained, the octahedral geometry was suggested for all ligand complexes exception of the Au(III) complex, which had a square planar geometry.
