The Synthesis and Characterization of s‐Triazine‐Cored Tripodal Structure and Its Salen/Salophen‐Bridged Fe/Cr(III) Capped Complexes

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 (salenH2)/bis(salicylidene)-o-phenylenediamine (SalophenH2). The synthesized ligand and complexes were characterized by means of elemental analysis carrying out 1H NMR, FTIR spectroscopy, thermal analyses, and magnetic susceptibility measurements. Finally, metal ratios of the prepared complexes were determined by using atomic adsorption spectrometry.
