title: Potassium ditin(IV) tris-[phosphate(V)], KSn(2)(PO(4))(3).
abstract: The title compound, KSn(2)(PO(4))(3), belongs to the NASICON-type family of phosphates with the space group R[Formula: see text]. Its structure is constructed by very regular [with P-O distances ranging from 1.513 (6) to 1.522 (6) Å] PO(4) tetra-hedra and SnO(6) octa-hedra on the 3. axis, which are linked by O atoms, forming an [Sn(2)(PO(4))(3)] framework. The K atoms occupy the [Formula: see text]. axis sites and are located in the voids of this arrangement. The crystal studied was a merohedral twin with twin law (010 100 00[Formula: see text]) and a component ratio of 0.580 (7):0.420 (7).
