Description
Summary:Complexes of nickel(II) with the composition Ni v O w (Imid) x A y · zNH 3 or Ni v N w (Imid) x' A y' · zNH 3 where Imid represents the imidazole molecule and A the anion of aspartic acid, picolinic acid, glutaric and glutamic acids, N-acetylglycine or histidine, have been synthesized. The results of thermal and spectral studies are analysed for the various complexes. The TGA curves and diffuse reflectance spectra are reported. Calculated electronic transitions are in good agreement with those observed. The monomeric or dimeric character of these complexes is shown. The nickel ions seem to be in an octahedral environment.
