Abstract
Synthesis, characterization and thermogravimetric behavior of Ni(II), Cu(II) and Zn(II) complexes of Schiff bases derived from 4-phenyl-1,3,5-triazine-2,6-diamine and 5-chloro- salicylaldehyde (H2L1), 5-bromo-salicylaldehyde (H2L2) has been reported. The ligands were characterized by FT-IR, 1H and 13C NMR, UV-Vis spectroscopy as well as elemental analysis. Spectral studies reveal that the ligands were acting as tetradentate chelating agents and coordinated to the metal center via deprotonated phenolate oxygen and azomethine nitrogen atoms in a 1:1 ligand to metal ratio. Thermal behavior of the complexes has been evaluated using thermogravimetric analysis (TGA). All complexes show similar modes of three steps weight loss process upon heating to 800 oC with gradual loss of organic and inorganic parts. The residues after heating correspond to metal oxides, with copper complexes were found to be the most thermally stable.References
