摘要：

Far-infrared (30-350 cm-1) and low frequency Raman spectra have been studied for a series of complexes MX2(pyridine) where M = Mn, Co, Ni or Cd, and X = Cl or Br. Assignments of v(MX) and v(MN) modes have been made, assisted by noting shifts in the bands on replacing the pyridine ligand by pentadeuteriopyridine. The results are compatible with, and lend support to, a structure comprising doublestrand halogen-bridged polymeric chains in which each metal atom is surrounded by one pyridine ligand, two-bico-ordinate halogen atoms, and three trico-ordinate halogen atoms. The results provide the most definitive basis so far for structural diagnosis of compounds of this stoicheiometry. © 1979.
