Abstract
A new compound in the Bi/Ca/V/O system has been found, and its structure de termined from single crystal X-ray diffraction data. The new compound, Bi2C aV2O9, is monoclinic with n=7.096(2), b=12.400(2), c=9.397(1) Angstrom, bet a=107.19(2)degrees, and Z=4. The two crystallographically distinct VO4 tetr ahedra do not share corners. Thus, there is one oxygen which is not part of a VO4 tetrahedron, and the structural formula may be written as Bi2Ca(VO4) (2)O. Mixing of Bi3+ and Ca2+ occurs on three sites where coordination to o xygen is seven or eight. (C) 2000 Elsevier Science Ltd. All rights reserved .
