Abstract

New Dinuclear methoxo-bridged manganese (III ) complex [Mn2 ( (MeO-bph)en)2Cl2 (-CH3O )2] (1 ) was synthesized by template reaction of 2-hydroxy-4-methoxybenzophenone, 1, 2-ethanediamine and MnCl2. 6H2O with molar ration (1: 1: 1) in methanol as solvent. The title compound 1 was characterized by elemental analyses (CHN ), Fourier Transform infrared spectroscopy (FT-IR ) and single crystal X-ray diffraction. X-ray result reveal that 1 is dimeric with methoxo bridges between two symmetry equivalent manganese ions. The Mn ions are surrounded in a distorted octahedral geometry influenced by Jahn-Teller effect. The tridentate Schiff base ligand MeO-bp-en and one of the methoxo-bridges bind in the equatorial mode, whereas in the axial positions, other metoxo-bridge and Cl atom bind to the Mn ions. Thermogravimetric analysis of 1 was studied and display the title compound 1 decompose in three stages. Finally, by calcination of 1 at 500  C for 3 h, we prepared Mn2O3 particles and characterized by FT-IR, XRD and SEM.
