SYNTHESIS, CHARACTERIZATION OF CYANIDE COMPLEXES WITH 2-(HYDROXYMETHYL)PYRIDINE BY VIBRATIONAL SPECTROSCOPIC, THERMAL STUDIES AND ELECTRICAL PROPERTIES

Abstract

In this investigation, we present synthesis and characterized of three new heteropolynuclear cyanide complexes with 2-(Hydroxymethyl)pyridine (hmpH) of [M(H2O)(hmpH)Ni(CN)4]2·nH2O, (M(II) = Fe, Co and Ni); n = 12 for Fe, 2 for Co and Ni). The obtained complexes have been studied by elemental, thermal analysis, FT-IR, and Raman spectroscopic measurement techniques. Considering the alterations in characteristic peaks of cyanide, aqua, and hmpH ligands, general knowledge about the structural features of the complexes was detected from the vibrational spectra. The Ni(II) ion is coordinated by four cyanide-carbon atoms forming a square planar geometry. In addition, thermal analyses and electrical features of the complexes were investigated.
