ABSTRACT:

The ligand 2-(acetylacetonato)-iminobenzohydroxamic acid and its different mixed ligand novel complexes with NiII having specific formulae have been synthesized and characterised by elemental analyses, magnetic and conductance measurements, IR and electronic spectral studies. The ligand was found to behave in dibasic tetradentate (OO’ NO donor) manner. All the synthesized NiII complexes were non-electrolyte with magnetic moment ranging from 2.92 to 3.10 BM. The structural assessment of the complexes has been carried out based on electronic, infrared and molar conductivity values. All the complexes were found to be of octahedral geometry.
