The FT-IR spectra of pyrazinamide complexes of transition metal(II) tetracyanonickelate

Abstract

M(PZA)(2)Ni(CN)(4) (where M = Mn, Co,Fe, Ni or Cd; PZA = pyrazinamide} complexes have been prepared for the first time and their FT-IR spectra are reported in the 400-4000 cm(-1) region. The spectral features suggest that the compounds are similar in structure to the Hofmann type two dimensional coordination polymer compounds, formed with Ni(CN)(4)(-2) ions bridged by M(PZA)(2)(+2) cations. PZA is coordinated to M(II) through the oxygen atom of the carbonyl group. (C) 2002 Elsevier Science B.V. All rights reserved.
