Synthesis, characterization and structural determination of some nickel(II) complexes containing imido Schiff bases and substituted phosphine ligands

The new amido tridentate ONN Schiff base complexes of [NiL(PR3)] were synthesized and chracterized by IR, UV-Vs, NMR and elemental analysis. Coordination geometry of [NiL1(PPh3)] was determined by X-ray crystallography. The thermogravimetry of the complexes were carried out in the range of 20-600 °C.
