Abstract
EXAFS measurements on (3-chloroanilinium)8(CuCl6)Cl4 in the solid stat e show conclusively that the-CuCl64- complex ions do not have the (unu sual) tetragonally compressed geometry (a) attributed to them in an ea rlier X-ray crystal structure analysis. The CuCl64- ions have a normal , tetragonally elongated geometry with a significant orthorhombic comp onent (b). Disorder of the CuCl64- ions in the crystal (b) accounts fo r the original crystallographic data. The, tetragonally elongated coor dination geometry of the CuCl64- ions is consistent with the optical a nd electron paramagnetic resonance spectra of the compound.
