A new compound with a non-centrosymmetric structure, potassium tetra-kis-[dioxomolybdenum(IV)] arsenate trioxide, K(MoO2)4O3(AsO4), has been synthesized by a solid-state reaction. The (MoO2)4O3(AsO4) three-dimensional framework consists of single arsenate AsO4 tetra-hedra, MoO6 octa-hedra, MoO5 bipyramids and bi-octa-hedral units of edge-sharing Mo2O10 octa-hedra. The [Mo2O8]∞ octa-hedral chains running along the a-axis direction are connected through their corners to the AsO4 tetra-hedra, MoO6 octa-hedra and MoO5 bipyramids, so as to form large tunnels propagating along the a axis in which the K(+) cations are located. This structure is compared with compounds containing M 2O10 (M = Mo, V, Fe) dimers and with those containing M 2O8 (M = V) chains.
通过固态反应合成了一种具有非中心对称结构的新型化合物——三氧化四[二氧代钼(IV)]砷酸钾，K(MoO2)4O3(AsO4)。(MoO2)4O3(AsO4)三维骨架由单个砷酸根AsO4四面体、MoO6八面体、MoO5双锥体以及边共享Mo2O10八面体的双八面体单元组成。沿a轴方向延伸的[Mo2O8]∞八面体链通过其角与AsO4四面体、MoO6八面体和MoO5双锥体相连，从而形成沿a轴延伸的大隧道，K(+)阳离子位于其中。将该结构与含有M 2O10（M = Mo、V、Fe）二聚体的化合物以及含有M 2O8（M = V）链的化合物进行了比较。
