| Summary: | The structure of the title compound trisodium aluminium bis(arsenate), Na3Al(AsO4)2, is built up from AlO4 and AsO4 corner-sharing tetrahedra, forming an undulating two-dimensional framework parallel to (100). The layers are constituted of large Al6As6O36 rings made up from six AlO4 and AsO4 tetrahedra in which two sodium cations are situated, the third sodium cation being located in the interlayer space. The structural relationships between the title compound and Na3Fe(PO4)2, NaAlCo(PO4)2 and Al5Co3(PO4)8 are discussed. |
