Synthesis and Characterisation of Co (II), Ni (II) and Cu (II) Complexes with Sodium Salt of p-Methoxyisonitrosoacetophenone

R. M. Patil and M. M. Prabhu

In the present studies, the complexes of Co (II), Ni (II) and Cu (II) were prepared with sodium salt of p-methoxyisonitrosoacetophenone and characterized by elemental analysis, electrical conductance, magnetic susceptibility, spectral techniques like UV-Visible, IR, NMR and thermal studies. Analytical data support 1 : 2 stoichiometry for metal : ligand. The molar conductivity data indicate that the complexes are non electrolytic in nature. The electronic spectra along with magnetic data suggest octahedral geometry for Co (II) and Ni (II) complexes and distorted tetrahedral geometry for Cu (II) complex
