Leena Salah Ibrahim, Elmugdad Ahmed Ali, Mohammed Sulieman Ali

At the present work salicylhydroxamic acid and its complexes with iron (III), cobalt (II) and manganese (II)were studied. Firstly, salicylhydroxamic acid had been prepared by the reaction of methyl salicylate and free hydroxylamine and was characterized by its melting point, (169 ?C), FT-IR showed characteristics spectral bands at 3288cm-1due to (OH) stretching vibration, 1614 cm-1 due to (C=O) and 907 cm-1 due to (N-O). The 1H NMR spectrum shows the characteristic attachment of the proton of the hydroxyl group to the nitrogen atom in the region 11.41 ? 12.20 ppm, the appearance of protons of aromatic ring in the region 6.83 ?7.832ppm. Iron (III), cobalt (II) and manganese (II) salicylhydroxamate complexes were prepared by reacting salicylhydroxamic acids with corresponding metal salts. The compounds were characterized using elemental analysis, spectral (infrared, UV-Vis), TGA and magnetic susceptibility. The purity of the complexes was confirmed by CHN analysis. The result indicates that the reaction between iron (III) and cobalt (II) with SHA (salicylhydroxamic acid) at 1:2 molar ratio but with manganese (II) was 1:1 molar ratio. They show absorbance at a wavelength of maximum (?max) 470nm, 351 nm and 300 nm for Fe3+, Mn2+and Co2+ respectively indicating that the metal ligand complexes were formed. The complexes were characterized by FT-IR characteristics spectral which showed bandsat1597- 1601 cm-1 (C=O) and 915-925 cm-1 (N-O), TGA thermogram of all complexes has shown three characteristics mass loss and residue mass as metal oxide. The spectral study analysis reveals that all complexes coordinated to the metal via oxygen atoms (O, O) in bidentate to form octahedral for [Fe (SHA2).Cl2]2H2O, tetrahedral for [Co (SHA)2]H2O and square pyramidal geometry for [Mn (SHA)Cl.H2O]H2O.
