Synthesis and redetermination of the crystal structure of NbF5

Single crystals of NbF5, niobium(V) fluoride, have been obtained by the reaction of niobium metal in a stream of dilute elemental fluorine at 473   K and subsequent sublimation. The as-obtained bulk phase compound was shown to be pure by powder X-ray diffraction at 293   K and by IR and Raman spectroscopy. A single-crystal X-ray analysis was conducted at 100   K. In comparison to the previously reported structure model [Edwards (1964). J. Chem. Soc. pp. 3714 – 3718], the lattice parameters and fractional atom coordinates were determined to much higher precision and individual, anisotropic displacement parameters were refined for all atoms.
