Аннотация:The anion-excess ordered fluorite-related phase Ba4Bi3F17 has been synthesized by a solid state reaction of BaF2 and BiF3 at 873K. The crystal structure of Ba4Bi3F17 has been studied using electron diffraction and X-ray powder diffraction (a = 11.2300(2) Angstrom, c = 20.7766(5) Angstrom, S.G. R3, R-I = 0.020, R-P = 0.036). Interstitial fluorine atoms in the Ba4Bi3F17 structure are considered to form isolated cuboctahedral 8 : 12 : 1 clusters. The structural relationship between Ba4Bi3F17 and similar rare-earth-based phases is discussed. (C) 2003 Elsevier Inc. All rights reserved.
