Triethylene Tetramine and Diethylene Triamine Based Schiff Base Complexes of Cerium(IV)

Schiff base complexes of Ce(IV) formed from salicylaldehyde/ acetophenone and L = triethylene tetramine (trien)/diethylene triamine (dien) namely [Ce(2)(L-4H)(CHC(6)H(4)O)(2)(C(2)O(4))(3)]center dot xH(2)O x = 1 or 2, [Ce(2)(L-4H)(CCH(3)C(6)H(5))(2)(C(2)O(4))(3)(OH)(2)]center dot H(2)O are reported. The complexes have been characterized by elemental and thermal analysis, magnetic and conductivity studies, IR. NMR and UV-visible spectroscopic studies. Some of the complexes show promising antibacterial activity against Bacillus subtilis, Streptococcus mutans, E. coli, Staphylococcus aureus and Pseudomonas aeruginosa.
