A new vanadium oxide, potassium bis-(dioxovanad-yl) phosphate, β-K(VO2)2(PO4), has been synthesized by a solid-state reaction. In the title compound, the [V2PO8] framework is built up from infinite pyramidal [V2O8]∞ and [VPO7]∞ chains linked together by V-O-P bridges, leading to a three-dimensional framework which delimits two types of inter-secting tunnels running along [100] and [010] in which the four unique K(+) ions, showing coordination numbers of nine and ten, are located.
一种新的钒氧化物，磷酸双（二氧化钒基）钾，β-K(VO2)2(PO4)，已通过固相反应合成。在标题化合物中，[V2PO8]骨架由无限的金字塔形[V2O8]∞和[VPO7]∞链通过V-O-P桥连接而成，形成一个三维骨架，该骨架界定了两种沿[100]和[010]方向相交的隧道，四个独特的K(+)离子位于其中，其配位数分别为九和十。
