ABSTRACT: The 2-hydrazino-pyridine precursor has been widely used to prepare ligands of various kinds by condensation with carbonyl compounds. These types of ligands are suitable for synthesizing novel transition metal (II) complexes with inter-esting magnetic properties. In this context we have synthesized the ligand 1-(2-hy-droxy-phenyl-2-ethyl-idene)-2-(pyridin-2-yl)hydrazine (HL) which was used in the preparation of the mononuclear title complex, [Ni(C₁₃H₁₂N₃O)(C₁₃H₁₃N₃O)]NO₃·0.5H₂O. As a result of the presence of HL and L in the [{Ni(HL)(L)}]⁺ unit, the complex appears to be a supramolecular dimer composed of the Δ(-) and Λ(-) optical isomers, which are linked by
