Descripción
Sumario:The title potassium vanadium tungsten bis­(arsenate oxide) was synthesized by a solid-state reaction at 973 K. The crystal structure is isotypic with KVOPO(4) and contains a [MVAs(2)O(10)](∞) framework built up from single MO(6) (M = V+W) octa­hedra sharing corners with single VO(6) octa­hedra and AsO(4) tetra­hedra. This structure shows the existence of infinite [VAsO(8)](∞) and [MAsO(8)](∞) chains running along the a and c directions, respectively. All atoms are located on general positions. The metal position M is statistically occupied by 78% V and 22% W.
