  The title metal complexes were found to be crystalline which have been characterized by elemental analysis, electrical conductivity, magnetic susceptibility measurements, and spectral techniques viz, UV-Visible, FT-IR and NMR (1H-NMR and 13C-NMR). These complexes were air-stable, with high melting points and were soluble in methanol and some other organic solvents such as n-hexane, diethylether and DMSO. The molar conductance of 1 × 10-3 M solutions of the metal complexes in methanol at 27°C indicates that they behave as electrolytes. Both Cobalt(II) and Nickel(II) complexes of N-benzylideneaniline ligand show paramagnetic nature. The electronic studies along with magnetic data suggest a square planer geometry for both Co(II) and Ni(II) complexes. The peak in FT-IR spectra at 1627 cm-1 confirmed the υ(C=N) stretching vibration found in the free ligand. This band was shi.. View More»
