摘要：

Heating of NH4BiF4 at 285 degrees C under dry ammonia yields Bi3NF6 via the intermediate products NH4Bi3F10 and BiF3. Bi3NF6 is an air-sensitive grey powder decomposing under dry NH3 at 350 degrees C to form Bi metal. It crystallizes in the orthorhombic space group Pbcm, with a = 581.74(2), b = 570.18(2), c = 1851.13(5) pm, Z = 4. The structure was determined by X-ray and neutron powder diffraction data. Bi3NF6 belongs to the family of vernier phases M(n)X(2n+1), and represents the first member of the series with n = 3. The two-symmetry independent Bi atoms exhibit coordination numbers of eight.
