Abstract
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.
