New Bidentate Schiff-Base Complexes Derived from 4-Hydroxy benzaldehyde with Semicarbazide Urea and thio Urea

Abstract

AbstractThree types of Schiff-base have been prepared derived form 4-hydroxy benzaldehyde with semicarbazide , ureaand thio urea L1, L2, L3 respectively. All these were bidentate ligands reacted with Fe (II), Co(II) & Ni(II) ionsin 1:2 metal to ligand molar ration to form [M(L)2 Cl2] complexes.The complexes have been characterized by means of metal analysis M%, IR, UV-Visible spectroscopy andmagnetic moment measurement as well as the molar conductivity measurements
