SYNTHESIS AND CHARACTERIZATION OF POLYMER ANCHORED CU (II) COMPLEX SUPPORTED BY N, N’-BIS (2-HYDROXY-3-METHYLBENZALDEHYDE) 4-METHYLBENZENE-1, 2-DIAMINE SCHIFF BASE

ABSTRACT

The free and polymer anchored copper ion complexes [HMBdMBn-Cu and P-HMBdMBn-Cu], supported by -ONNO-tetradentate Schiff-base ligand are prepared by the reactions of copper chloride solution with one molar equivalent of unsupported HMBdMBn (N, N’-bis (2-hydroxy-3-methylbenzaldehyde) 4-Methylbenzene-1,2-diamine) or polymer supported (P-HMBdMBn) Schiff-base ligands in methanol. The efficiency of complexation of copper ion on the polymer anchored HMBdMBn Schiff base was more than unsupported one. The structural study reveal that copper(II) ion complex of HMBdMBn Schiff base is square planar geometry. Complexation of copper ion increased the thermal stability of HMBdMBn Schiff base.
