Abstract
Nasicon-type trisodium discandium tris(arsenate), Na3Sc2(AsO4)(3), contains a polyhedral network of vertex-sharing octahedral ScO6 and tetrahedral AsO 4 units [d(av) (Sc-O) = 2.089 (2) Angstrom and d(av) (As-O) = 1.672 (2) Ang strom] encapsulating two types of Na+ species. The sodium site occupancies are similar to those of the equivalent species in beta -Na3Sc2(PO4)(3).
