Abstract: | The nickel(II)-di(2,3-dichlorophenyl)carbazonate [Ni(D2,3DClPC)2] complex has been prepared and characterized by elemental and spectral studies. The NiII chelate forms adducts with heterocyclic nitrogen bases, which were studied spectrophotometrically in monophase CHCl3 media. Saturated monodentate bases such as pyrrolidine, piperidine, etc., form pentacoordinate adducts of 1:1 stoichiometry, whereas bidentate and unsaturated monodentate bases form hexacoordinated adducts with 1:1 and 1:2 metal–ligand stoichiometries respectively. The results are discussed interms of steric properties, basicity and ring structures of the heterocyclic bases. |
