| Abstract | ||
| New α-(2-pyridyl)benzylidine (5-nitropyrid-2-yl)amine (L) ligand has been synthesized by condensation of 2-benzoyl pyridine and 2-amino-5-nitro pyridine in 1:1 molar ratio in ethanol. Further the Co+2,Ni+2 and Cu+2 complexes were synthesized by reacting above ligand with metal chloride in (1:1) (1:2) or (2:2) (Ligand:metal) molar ratio in ethanolic medium. The ligand and their complexes were characterized by electronic and IR spectra, magnetic susceptibility measurements, molar conductance and metal content analysis. The complexes (1-3) and (7-9) are found to be non ionic in nature while the complexes (4-6) are found to be (1:2) electrolyte. The magnetic moment and electronic spectral studies show a tetrahedral geometries for the complexes (1-6) and octahedral geometries for the rest of the complexes. | ||
