Synthesis and Spectroscopic Studies of Cu(II), Co(II), Ni(II) and Zn(II) Schiff Base Complexes from 1-Amino-5-benzoyl-4-phenyl-1H pyrimidine-2-on with 2-Hydroxynaphthaldehyde

Cu(II), Co(II), Ni(II) and Zn(II) metal complexes of a new heterocyclic Schiff base derived from 1-amino-5-benzoyl-4-phenyl-1H pyrimidine-2-on with 2-hydroxynaphthaldehyde have been synthesized and characterized by elemental analyses, electronic, IR and 1H NMR spectra, and also by molar conductivity and magnetic moment measurements. It has been found that the Schiff bases behave as a neutral tridentate (ONO) ligand, forming chelates with 1:2 (metal:ligand) stoichiometry. It is suggested that all the complexes have octahedral structure and are non-electrolytes.
