Abstract: The structure of the title compound tris-odium aluminium bis-(arsenate), Na(3)Al(AsO(4))(2), is built up from AlO(4) and AsO(4) corner-sharing tetra-hedra, forming an undulating two-dimensional framework parallel to (100). The layers are constituted of large Al(6)As(6)O(36) rings made up from six AlO(4) and AsO(4) tetra-hedra in which two sodium cations are situated, the third sodium cation being located in the inter-layer space. The structural relationships between the title compound and Na(3)Fe(PO(4))(2), NaAlCo(PO(4))(2) and Al(5)Co(3)(PO(4))(8) are discussed.
