Mixed metal Fe-Mo complexes with schiff bases of triethylenetetramine & diethylenetriamine


Mixed metal complexes of Fe(III) and tetrathiomolybdate have been synthesized with Schiff bases of triethylenetetramine (trien)/ diethylenetriamine (dien) formed from acetophenone and acetylacetone. The complexes are characterized by elemental and thermal analysis, IR, UVVisible spectral studies, magnetic and EPR studies. The complexes probably have a structure containing FeMoS4 cluster with ferric iron linked to a chloro ligand and two or four CH=N nitrogens of the trien/dien based Schiff bases. The complexes have a composition [(trien-4H) (CCH3C6H5)2 (FeMoS4) Cl]. H2O and [(dien-4H) (CCH3C6H5)2 (FeMoS4) Cl (H2O)] and [(dien-4H) (CH3CCH2CCH3)2 FeMoS4.Cl] and [(trien-4H) (CH3CCH2CCH3) FeMoS4.Cl]. 6H2O. The acetophenone Schiff base complexes of trien and dien show promising antibacterial activity against Bacillus cereus and Bacillus subtilis.
