The results of an EXAFS investigation of methanol and ethanol solutions of CoBr2 are reported. The curve fitting analysis gives the coordination numbers and the Co−Br and Co-solvent distances. The results for both 0.2M and 3.8M CoBr2 in ethanol show the existence of [CoBr2(C2H5OH)2] as the dominant species, although a considerable amount of octahedral species also exists in the solutions. In 0.2 and 3.3M CoBr2 methanol solutions, the dominant species are [Co(CH3OH)6]2+ and [CoBr(CH3OH)5]+, respectively.
