The structure of a bismuth based oxide, Bi2O3:V2O5=9:1, has been studied by X-ray diffraction. This crystal has a fluorite type superstructure with 3× 3× 3 subcells. Vanadium atoms are located at every third layers along the [111] axis and occupy the third neighbor sites of the fcc lattice. The oxygen vacancies are concentrated at nearest neighbor sites of the vanadium atoms.
