Abstract: | Six new Mn(II), Fe(II), Co(II), Ni (II), Cu(II) and Zn(II) complexes with benzoic acid (L) and 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione (L1), of the molecular formulae [MnLL1]·H2O (1), [FeLL1]·H2O (2),[CoLL1] (3), [NiLL1]·H2O (4), [CuLL1] (5) and [ZnLL1] (6), respectively, have been synthesized. The molecular structures of the complexes were determined by spectrophotometric studies using ir, 1H and 13C nmr, es and mass spectrophotometry revealed that the geometries of the complexes 1, 2, 3, and 6 are tetrahedral, while 4 and 5 have square planar geometry. These geometries were supported by their magnetic moments data. The coordination of the ligands to the metal ion are through their oxygen atoms. TGA studies showed that they are thermally stable. Their antioxidant studies revealed that they are good antioxidants. |
