A novel Schiff base compound was synthesized, and its complexation properties with Fe(III) and Cr(III) were investigated. Tripodal ligand was synthesized by the reaction of s-triazine and 4-hydroxybenzaldehyde. Then a Schiff base involving 8-hydroxyquinoline was synthesized by the reaction of 5-aminomethyl-8-hydroxyquinoline (QN) and 2,4,6-tris(p-formylphenoxy)-1,3,5-triazine (TRIPOD) in methanol/chloroform media. The obtained Schiff base (QN-TRIPOD) was then reacted with four trinuclear Fe(III) and Cr(III) complexes including tetradentate Schiff bases N,N′-bis(salicylidene)ethylenediamine (salenH 2 )/bis (salicylidene)-o-phenylenediamine (SalophenH 2 ). The synthesized ligand and complexes were characterized by means of elemental analysis carrying out 1 H NMR, FTIR spectroscopy, thermal analyses, and magnetic susceptibility measurements. Finally, metal ratios of the prepared complexes were determined by using atomic adsorption spectrometry.
