Abstract

The dependence of the Cl-→Cu2+ charge transfer (CT) band at 26 000 cm-1 with the local structure of the Jahn-Teller elongated CuCl4-6 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 CuCl4-6 related to the crystal dimensionality.
