Abstract
Complexes of the general formulas M(pyridine)2(CHxH3–xCO2)2 where x= 1, 2, or 3 and M = CoII, NiII, and CuII and X = F or Cl, have been characterised by vibrational and electronic spectroscopy, magnetism, conductivity, and molecular weight studies. The complexes are six co-ordinate and may be monomeric involving bidentate haloacetate groups, or dimeric according to the solvent and temperature. The visible absorption band of the cobalt haloacetate complexes shows structure interpreted in terms of tetragonal distortion.Keywords
