Infrared spectra (1650–400 cm.–1) of γ-picoline metal co-ordination complexes

Abstract

Infrared spectra (1650–400 cm.^–1) are reported for the following complexes of γ-picoline (L): ML₄X₂(M = Mn or Ni, X = Cl, Br, or I; M = Fe, X = Br; M = Co, X = Cl, Br, I, or NCS), ML₂X₂(M = Mn, Cu, Zn, X = Cl; M = Co, X = Cl, Br, or I; M = Ni, X = Br or I), and MLX₂(M = Mn, Ni, X = Cl). The changes from the spectrum of the free ligand are related to the polarising power of the metal ion and the geometry of the complex.
