摘要

The structure of the title compound tris-odium aluminium bis-(arsenate), Na3Al(AsO4)2, is built up from AlO4 and AsO4 corner-sharing tetra-hedra, forming an undulating two-dimensional framework parallel to (100). The layers are constituted of large Al6As6O36 rings made up from six AlO4 and AsO4 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 Na3Fe(PO4)2, NaAlCo(PO4)2 and Al5Co3(PO4)8 are discussed.
