In the reactions of Cu(II), Co(II), and Ni(II) chlorides with 2,3-butanedione and 2,4-pentanedione isonicotinoylhydrazones in neutral and weakly acid media complex compounds of the addition-product type are formed, but in an alkaline medium inner-complex compounds are formed. By methods of electronic and ESR spectroscopy it was shown that the Cu(II) complex compounds have a planar-square structure, the Ni(II) complexes are octrahedral, but the Co(II) complexes have a tetrahedral or distorted tetrahedral structure. In the spectrochemical series 2,3-butanedione and 2,4-pentanedione isonicotinoylhydrazones occupy positions between water and ammonia.
