摘要：
The title compound, potassium strontium trialuminium tetra-arsenate, was prepared by solid-state reaction. The structure consists of AlO6 octahedra (site symmetries 2.. and 2/m) and two AsO4 tetrahedra (.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.
