    Mixed ligand complexes of NiII    ion with 1-cyano-1-carboethoxyethylene-2,2-dithiolate   (CED2−[S2C   = C (CN)(COOC2H5)]2−)   as a primary ligand and   o-phenylenediamine   (OPD), pyridine (py), α-picoline (α-pic),   β-picoline   (β-pic)   or γ-picoline (γ-pic) as secondary ligands have been isolated and   characterized on the basis of analytical data, molar conductance,   magnetic susceptibility, electronic and infrared spectral   studies. The molar conductance data reveal that the complexes   have 1:1 electrolytic nature in DMF solution. Magnetic and   electronic spectral studies suggest distorted octahedral   stereochemistry around NiII    ion in its complexes. Infrared spectral studies suggest bidentate   chelating behaviour of CED2−    ion and OPD while other ligands show unidentate behaviour in   their complexes.
