Summary
2-Thenoyltrifluoroacetone isonicotinoyl hydra/one (H2L), made by condensation of 2-thenoyltrifluoroacetone(TTA) with isonicotinic acid hydrazide, and its transition metal complexes were prepared. H2L functions as a tetradentate ligand for divalent metal ions, but as a tridentate ligand for trivalent metal ions, taking part in coordination in both mono- and divalent anions. Antioxidative tests were made to examine the elimination action for H2L and the complexes towards superoxide O sup−.inf2 and hydroxyl OH. radicals, which confirmed the efficient antioxidative action towards these radicals.
