The compounds [Ni(Gly)2N-N].nH2O (n = 1, 2; Gly = glycine anion; N-N – ethylenediamine 1,10-phenanthroline, α,α’-bipyridyl) and K[Ni(Gly)3].3H2O were prepared. On the basis of their magnetochemical and spectral properties, the compounds obtained can be characterized as octahedral nickel(II) complexes. Cyclic voltammetry was employed to study the redox properties of selected compounds and possible electrochemical and chemical oxidation were studied. The results obtained permitted comparison with the properties of nickel(II) complexes with dipeptides or tripeptides as ligands.
