摘要：

Single crystals of Ba5Nb3O3F18(HF2) are grown by hydrothermal synthesis. The crystal structure is established from single-crystal X-ray diffraction data: S. G. P63/m, Z = 2, a = 11.935(1) Å, and c = 7.852(1) Å (R = 0.0249, Rw = 0.0255 for 819 independent reflections and 57 parameters). The tridimensional network is built up from NbX7 (X = O, F) pentagonal bipyramids connected by Ba2+ ions. The location of anions (O2-, F-, and [HF2]-) is discussed from bond valence calculations. © 1993 Academic Press, Inc.
