ABSTRACT:

The complexes of some micro-nutrient metals [Fe(III) , Mn(III) and Mn(II)] were prepared with thiosemicarbazide, 4-aminoantipyrine, 2-hydroxy5-methylacetophenone and 2-hydroxy5- chloro acetophenone , having general formula formula [Fe (C9H10N3SCl)2 2H2O]3Cl, [Mn (C9H10N3SCl)2 H2 O]3Cl [Fe (C20H20N3 O2)2 .]Cl; [Mn (C20H20N3O2)2.] Cl .and [Mn (C20H20N3 O2 )2 .] . These adducts have been characterized on the basis of elemental analyses, molar conductance, infrared, visible spectra, magnetic susceptibility measurements and TGA . The complexes prepared were screened for biological studies at IVRI Bareilly.The ligand behaves in bidentate manner. The complexes of Fe(III), Mn(III) and Mn(II) of 5-methyl2-hydroxyacetophenoneantipyrine and Fe(III),Mn(II) of 2-hydroxy5-chloroacetophenonethiosemicarbazone) are paramagnetic in character and have octahedral geometry . The complexes of Mn(III) of 5-methyl 2-hydroxy5- acetophenonethiosemicarbazone is also paramagnetic in nature and has square pyramidal geometry.

KEYWORDS:

Square pyramidal geometry; Octahedral geometry; Molar conductance
