A new potassium vanadium arsenate, tripotassium trivanadium bis-(arsenate) hexa-oxide, 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) tetra-hedra (.m. symmetry) and AsO(4) tetra-hedra 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 inter-connected tunnels running along the a and b directions.
一种新型砷酸钒钾，三钾二钒双（砷酸盐）六氧化物，K(3)VO(2)(V(2)As(2)O(12))，通过在743 K下的固态反应合成。其结构由VO(5)金字塔、VO(4)四面体（.m.对称性）和AsO(4)四面体通过共角连接在一起形成三维框架。两个晶体学独立的K(+)阳离子，其中一个具有.m.对称性，位于沿a和b方向延伸的相互连接的隧道中。
