Abstract
The title complex has been synthesized and characterized by elemental and spectral analysis. The Ni-II chelate forms adducts with heterocycl ic nitrogen bases, which were characterized spectrophotometrically in solution. Bidentate and unsaturated monodentate bases form hexacoordin ate adducts with 1:1 and 1:2 metal:ligand stoichiometries, respectivel y, whilst saturated nitrogen bases form pentacoordinate adducts with 1 :1 stoichiometry. The results are discussed in terms of basicities and steric properties of the bases.
