摘要：

Bi1.7V8O16 was synthesized by high temperature solid state reaction between Bi2O3, V2O5, and V2O3. The compound crystallizes with tetragonal symmetry, space group I4/m. The structure refinement using single crystal data confirms that the compound belongs to the hollandite family. It is the first hollandite-type compound containing bismuth in the large tunnels of the V8O16 framework. The bismuth atom forms a very flat BiO4 square pyramid with the skeleton oxygen atoms. Bi1.7V8O16 is oxidized to BiVO4 and V2O5 at 400°C in air, as evidenced by TGA and DSC. © 1994 Academic Press, Inc.
