Synthesis,Characterization and X-Ray Diffraction Studies of Co(II),Ni(II),Cu(II) and Zn(II) Complexes with Schiff Base Derived from 5-Nitrosalicylaldehyde and Anthranilic Acid

摘要

Transition metal (II) complexes of the type MLnH2O [where M-Co(II),Ni(II),Cu(II) and Zn(II),L-Schiff base derived from 5-nitro salicylaldehyde and anthranilic acid,n=0,1...] have been prepared and characterized by elemental analysis,molar conductivity,IR,electronic spectra,magnetic susceptibility studies and X-ray difraction spectra.Molar conductivity measurements indicate that the complexes are non-electrolytic in nature.From the analytical and spectral data,the stoichiometry of the complexes has been found to be 1:1 (metal:ligand).IR spectral data suggests that the ligand behaves as a monobasic tridentate ligand with O:N:O donor sequence towards metal ions.Magnetic susceptibility measurements indicate paramagnetic behaviour of all the complexes except Zn-complex.X-ray diffraction studies suggest monoclinic crystal'system for these complexes.
