Abstract
Several adducts of nickel(II) carboxylates with the general formula [NiL2(O2CR)2] have been prepared [R = Me, Ph, 4-ClC6H4, and 2-NO2C6H4; L = pyridine (py), 2-methylpyridine (2-Mepy), and quinoline (quin)]. All the complexes have been shown to be six-co-ordinate by magnetochemical and electronic-spectral measurements. Analysis of the tetragonal splitting of their diffuse-reflectance spectra at low temperature and of the polarized single-crystal spectrum of [Ni(py)2(H2O)2(O2CMe)2] indicates that all the complexes adopt the trans-configuration except [Ni(2-Mepy)2(O2CPh)2] which shows the cis-configuration. No clear evidence has been found for formation of dimeric complexes.Keywords
