摘要

The dependence of the Cl~- -> Cu~(2+) charge transfer (CT) band at 26000 cm~(-1) with the local structure of the Jahn-Teller elongated CuCl_6~()4- unit is investigated. For this purpose we report hydrostatic pressure experiments performed on the title compounds. The results indicate that the first CT band experiences a pressure-shift of - 1000 and + 1200 cm~(-1) in the 0-80 kbar range for each compound, respectively. This different shift in behaviour is explained by the distinct anisotropic compression of CuCl_6~(4-) related to the crystal dimensionality.
