Preparation and Identification of Cr(III), Fe(II), Fe(III), Mn(II) and Hg(II) Complexe with 4-[N-(Salicyladehyde) imino] Antipyrinyl Semicarbazide Ligand (L1)

Abstract

Complexes of the new ligand 4[N-(Salicylaldehyde) imino] antipyrinyl semicarbazide ligand (L1) with the metal ions Cr (III), Fe(II), Fe(III), Mn(II) and Hg(II) have been synthesized and characterized on the basis of physiochemical investigations included infrared and electronic spectroscopy, magnetic moment measurement, molar conductance and elemental analysis .The above studies Infrared spectral data suggest that the ligand L1 behaves as tetradentate ligand and was coordinated through (N, N, O, O) donor atoms sequence towards the metal ions, and it gives an octahedral complexes in molar ratio 1:1 Metal: Ligand. While it behaves as bidentale towards the metal ions in molar ratio 1:2 (M:L) resulting in four coordinated complexes. On the basis of the above physicochemical data, an octahedral and four coordinated geometries were assigned for the complexes.
