III-Preparation and characterization of some Zn+2 , Cd+2, and Hg+2 complexes with Derivatives

Abstract

This research consists of the synthesis of some Schiff bases the following types: 1, 3 - Bis - (2-hydroxy-benzylidene) - thiourea = (L1) 1, 3 – Bis - (2-hydroxy-benzylidene) - urea = (L2) The complexation of these ligands with some of transition metal ions (Zn+2 , Cd+2, and Hg+2(.The Schiff bases together with their corresponding prepared transition metal complexes have been characterized on the bases of their (C.H.N) elemental analysis, IR, UV-VIS, and atomic absorption. Molar conductivity measurement and melting point of prepared complexes were measured. Their structures were propose according to the obtained results.
