Abstract
The fluorides CuMoF6 and CrNbF6 are triclinic, isostructural with CuSn F6. Their crystal structures were solved in the space group P (1) over bar, by the Rietveld method using the data of their X-ray powder patt erns. Both crystal structures can be described as a three-dimensional framework of alternating 6 corner-sharing [(MF6)-F-II] and [M'F-IV(6)] octahedra (M-II = Cr, Cu; M'(IV) = Nb, Mo) with ferrodistortive Jahn- Teller ordering.
