K(3)VO(2)(V(2)As(2)O(12))

A new potassium vanadium arsenate, tripotassium trivanadium bis­(arsenate) hexa­oxide, K(3)VO(2)(V(2)As(2)O(12)), was synthesized by a solid-state reaction at 743 K. The structure is built up from VO(5) pyramids, VO(4) tetra­hedra (.m. symmetry) and AsO(4) tetra­hedra linked together by corner-shari...

Sumario:A new potassium vanadium arsenate, tripotassium trivanadium bis­(arsenate) hexa­oxide, K(3)VO(2)(V(2)As(2)O(12)), was synthesized by a solid-state reaction at 743 K. The structure is built up from VO(5) pyramids, VO(4) tetra­hedra (.m. symmetry) and AsO(4) tetra­hedra linked together by corner-sharing to form a three-dimensional framework. The two crystallographically independent K(+) cations, one of which has .m. symmetry, are located in the inter­connected tunnels running along the a and b directions.
