The reaction of 2-picolyl and 2-quinaldylphenyl ketones with nickel(II), cobalt(II) and copper(II) ions was investigated. Magnetic and spectral data were used to determine the structure of the complexes. Both ketones react with Cu(II), forming distorted tetrahedral complexes, while the Ni(II) ion forms a square planar complex with a 2-picolylphenyl ketone and a tetrahedral complex with a 2-quinaldylphenyl ketone. The reaction with the Co(II) ion gave a highspin tetrahedral complex with a 2-picolylphenyl ketone and a five coordinate polymeric type with a 2-quinaldylphenyl ketone. The solution spectra of the complexes as well as their base adducts were also investigated.
