Abstract
Structures of solutes in copper(II)acetate aqueous and ethanolic solutions in both liquid and glassy states are determined by means of EXAFS and XANES. The solute in the aqueous solution has monomeric structure in both states. It has four short Cu-O bonds (195pm) and two longer bonds (228pm) in glassy water-glycerol mixed solution. On the other hand, it has dimeric structure similar to its crystalline state in both states of ethanolic solutions. Weaker interactions such as Jahn-Teller elongation and nonbonded interatomic pairs are clarified by vitrifying the solutions and information on non-uniform Cu-O bond lengths are extracted by comparing the EXAFS spectra of solutions in the liquid and glassy states.
