New Schiff base ligand [H2L] with 4N donor atoms moiety was prepared by reacting amine derivative of o-phenylenediamine hydrazide moiety with benzaldehyde.Co(II), Ni(II), Cu(II) and Zn(II) of the new Schiff base were prepared by using a molar ratio of ligand: metal as (1:1).The structure of the Schiff base and the prepared complex was determined by 1 H NMR, UV-Vis, IR, Mass spectrometry and molar ...
