摘要：

Single crystals of Ba4Nb2O3F12 were grown by hydrothermal synthesis. The structure is determined from X-ray diffraction data: space group C2/c, Z = 12, a = 22.672(2) Å, b = 13.075(1) Å, c = 14.996(1) Å and β = 114.234(5)° (R = 0.0227 and Rw = 0.0282 for 6886 independent reflections and 288 parameters). The network is built up from separated [Nb4O7F14]8- blocks of four cis -oxygen linked distorted octahedra (2 × NbO2F4 and 2 × NbO3F3) and from isolated NbOF6 pentagonal bipyramids. All these entities are three-dimensionally connected by classically coordinated Ba2+ ions. © 1993 Academic Press, Inc.
