Abstract: Single crystals of trilithium(I) aluminium(III) bis[dioxidomolybdenum(VI)] dioxide bis[arsenate(V)], Li₃AlMo₂As₂O₁₄, have been prepared by solid-state reaction at 788 K. The structure consists of AsO₄ tetrahedra, AlO₆ octahedra and Mo₂O₁₀ 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 (MX₂O₁₂)_n chains (M = Mo, Al and X = P, As) and others containing M₂O₁₀ (M = Mo, Fe) dimers.
