Cobalt complexes of the type, ML2.nH2O , ML2.HL and ML3 have been prepared and characterized.The IR data suggest N- and O-bondings of the oximino group in one and the same molecule of the complex, the exception being 4-NO2 substituted complex where bonding occurs through isonitroso nitrogen only.Substitution in the phenyl ring of the complexes produces shifts in ν(C=O) which are related to the Hammett's substituents parameters.The magnetic moments observed for the cobalt(II) complexes, except that of 4-NO2 substituted complex, indicate distorted octahedral geometry.The PMR spectra of cobalt(III) chelates with 4-MeHINAP and 4-OMeHINAP suggest a cis octahedral structure for these complexes.
