“…The vapor pressure (Junkins et al, 1952;Fairbrother & Frith, 1951), the enthalpy of fusion (Junkins et al, 1952), and the electrical conductivity (Fairbrother et al, 1954) of liquid NbF 5 have also been determined. Infrared and Raman spectra of the solid were measured (Preiss & Reich, 1968;Beattie et al, 1969) and the structure of NbF 5 in the (supercooled) liquid, glassy state and the gas phase have been investigated by Raman spectroscopy (Boghosian et al, 2005;Papatheodorou et al, 2008). In a search for a suitable laboratory synthesis of NbF 5 , we investigated several methods for its preparation.…”

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.
