✦ Synopsis

The fluorides CuMoF 6 and CrNbF 6 are triclinic, isostructural with CuSnF 6 . Their crystal structures were solved in the space group P1, by the Rietveld method using the data of their X-ray powder patterns. Both crystal structures can be described as a three-dimensional framework of alternating 6 corner-sharing [M II F 6 ] and [M' IV F 6 ] octahedra (M II = Cr, Cu; M' IV = Nb, Mo) with ferrodistortive Jahn-Teller ordering.
