Preparation and Characterization of Biacetyl Monoxime Hydrazone Salicylidene Complexes of Lanthanoid (III) Ions

The 1:3 complexes of lanthanoid (III) ions as Nd(III), Sm(III), Tb(III) and La(III) with biacetyl monoxime hydrazone salicyalidene have been prepared and characterized by elemental analysis, IR, PMR, electronic spectra, molar conductance and magnetic properties. All these complexes of Ln(III) complexes are found to be unique in infrared and solubility to the methanol, chloroform, DMF, DMSO solvents. The results show that the biacetyl monoxime hydrazone salicyalidene ligand acts as a bidentate monobasic donor, coordinating through the azomethine nitrogen and deprotonated oximino proton.
