Deskripsi
The title compound, KSn2(PO4)3, belongs to the NASICON-type family of phosphates with the space group Roverline{3}. Its structure is constructed by very regular [with P—O distances ranging from 1.513 (6) to 1.522 (6) Å] PO4 tetrahedra and SnO6 octahedra on the 3. axis, which are linked by O atoms, forming an [Sn2(PO4)3] framework. The K atoms occupy the overline{3}. axis sites and are located in the voids of this arrangement. The crystal studied was a merohedral twin with twin law (010 100 00overline{1}) and a component ratio of 0.580 (7):0.420 (7).
