Synthesis and characterization of octahedral Ni(II) complex with condensation product of 2-acetylpyridine and Girard's P reagent

Abstract

The ligand ([HL]Cl) was synthetized by the reaction of 2-acetylpyridine and Girard's P reagent in molar ratio 1:1 in ethanol. In the reaction of ligand ([HL]Cl), nickel(II) tetrafluoroborate hexahydrate and sodium azide [Ni(HL)(N3)3] complex was obtained. The Ni(II) ion has a distorted octahedral coordination geometry. The tridentate ligand (HL) is coordinated to the nickel ion with an NNO set of donor atoms forming two five-membered chelate rings and the other three coordination sites are supplemented by azido ligands. The ligand (HL) and the [Ni(HL)(N3)3] complex were characterized by elemental analysis, IR and UV/Vis spectroscopy and structure of the complex was defined by X-ray analysis.
