Fourier transform infrared and Raman spectroscopic studies on 4- tert.-butylpyridine and its metal(II) tetracyanonickelate complexes

Abstract

Infrared and Raman spectra of 4- tert.-butylpyridine (4- tbpy) are reported for the first time in the 4000–200 cm −1 range. Vibrational assignments have been made for fundamental modes on the basis of frequency shifts of the coordinated ligand, and comparison with related molecules. The infrared and Raman spectra of M(4- tbpy) 2Ni(CN) 4 (where M=Mn, Cd, Fe, Co or Ni; abbreviated to M-Ni-4- tbpy) complexes are reported for the first time. It is shown that the structure of these complexes consists of infinite polymeric layers of [M-Ni(CN)4] ∞ analogous to those of Hofmann-type complexes. 4- tbpy molecules bound directly to the metal (M). © 1997 Elsevier Science B.V.
