Abstract:

Transition metal ions have been extensively used as catalysts for affecting a number of reactions. In recent times, the studies on the use of transition metal ions either alone or as binary mixtures as catalysts in many redox reactions have been gaining interest. Their oxidizing and catalytic activities are due to the existence of variable oxidation states, as a consequence of partly filled d or f orbital. In the present study, we have synthesized the Mn(II) and Ni(II) picrate complexes with 1,1- dimethylhydrazine and characterized them  on the basis of elemental analysis, molecular  weight determination, metal estimations, magnetic moments, I.R., U.V. and E.S.R. spectral studies. The complexes are coloured and quite stable at room temperature, insoluble in common organic solvents but soluble in DMF and DMSO. Magnetic and spectral studies confirm that the complexes were octahedral and the ligand was bidentate innature.
