Abstract
The ligands 2,4-bis(2-hydroxyphenyliminomethyl)-6-methyl-1,3,5-triazine (AGSAL), 2,4-bis(2-carboxyphneyliminomethyl)-6-methyl-1,3,5-triazine (AG2FBA), and 2,4-bis(4-carboxyphneyliminomethyl)-6-methyl-1,3,5-triazine (AG4FBA) were prepared with a Schiff base condensation between acetoguanamine and the corresponding salicylaldehyde, 2-formylbenzoic acid, and 4-formylbenzoic acid. High-spin (S = 5/2) complex [FeIII(AGSAL)Cl] was obtained by complexation of AGSAL with FeCl3. Then, binuclear complexes [{FeIII(AGSAL)}2(AG2FBA)] and [{FeIII(AGSAL)}2(AG4FBA)] were prepared by combination of [FeIII(AGSAL)Cl] and “(AG2FBA), (AG4FBA),” respectively. Then, trinuclear complexes [{FeIII(AGSAL)}2(FeIIIAG2FBA)] and [{FeIII(AGSAL)}2(FeIIIAG4FBA)] of the ligands were prepared by reaction of the binuclear complexes and FeCl3 salt. A weak antiferromagnetic exchange was found for all complexes. Finally, the structures of ligands and complexes were identified by using elemental analysis, magnetic susceptibility, 1H NMR, 13C NMR and FT-IR spectral data.
