Single crystals of trilithium(I) aluminium(III) bis-[dioxidomolybdenum(VI)] dioxide bis-[arsenate(V)], Li(3)AlMo(2)As(2)O(14), have been prepared by solid-state reaction at 788 K. The structure consists of AsO(4) tetra-hedra, AlO(6) octa-hedra and Mo(2)O(10) groups sharing corners to form a three-dimensional framework containing channels running respectively along the [100] and [010] directions, where the Li(+) ions are located. This structure is compared with compounds having (MX(2)O(12))(n) chains (M = Mo, Al and X = P, As) and others containing M(2)O(10) (M = Mo, Fe) dimers.
通过在788 K下进行固态反应制备了双[二氧化钼(VI)]二砷酸根(Ⅴ)三锂(Ⅰ)铝(Ⅲ)单晶，Li(3)AlMo(2)As(2)O(14)。该结构由AsO(4)四面体、AlO(6)八面体和Mo(2)O(10)基团通过共用角形成三维骨架，该骨架包含分别沿[100]和[010]方向延伸的通道，Li(+)离子位于这些通道中。将该结构与具有(MX(2)O(12))(n)链（M = Mo、Al且X = P、As）的化合物以及其他含有M(2)O(10)（M = Mo、Fe）二聚体的化合物进行了比较。
