Abstract
In this study, three new immobilized Schiff bases and their Co(II), Cu(II) and Ni(II) metal complexes have been prepared. The ligands silica-Si[N-(3-propyl)2,4-dihydroxybenzaldimine] (1) H2L, silica-Si[N-(3-propyl)4-methylsalicylaldimine-3-methoxy] (2) HL and silica-Si[N-(3-propyl)2-pyridinecarboxyaldimine] (3) L have bidentate characters. Therefore, the complexes are the mononuclear. Ligands and metal complexes were characterized by FTIR, AAS and thermoanalytical techniques. On the basis of analytical data and IR studies, a 1:1 metal to ligand stoichiometry has been suggested. TG and DTA results showed that these ligands and complexes had good thermal stability. The heat capacities of ligands were reported in the temperature range 273–363 K as no thermal anomaly was found in this temperature range.
