title: The aluminoarsenate K(1.8)Sr(0.6)Al(3)(AsO(4))(4).
abstract: The title compound, potassium strontium trialuminium tetra-arsenate, was prepared by solid-state reaction. The structure consists of AlO(6) octa-hedra (site symmetries 2.. and 2/m) and two AsO(4) tetra-hedra (.2. and m..) sharing corners and edges to form a two-dimensional structure parallel to (010). The cations are occupationally disordered and are located in the interlayer space. For both types of cations, distorted coordination polyhedra are observed.
