The preparation and properties of niobium tetrafluoride and oxyfluorides
Gortsema,Didchenko
, p. 182 - 186 (1965)
Niobium tetrafluoride has been prepared by the reduction of niobium pentafluoride with Si or Nb powder at 300-350°. X-Ray diffraction studies of the tetrafluoride show that it has a tetragonal unit cell with a0 = 4.081 and c0 = 8.162 A?. Reduction of NbF5 in sealed quartz tubes with red phosphorus, arsenic, or silicon gave rise to a series of very stable niobium oxyfluorides having the same structure as NbF3.
