• NASICON

The title compound, KSn2(PO4)(3), belongs to the NASICON-type family of phosphates with the space group R (3) over bar. Its structure is constructed by very regular [with P-O distances ranging from 1.513 (6) to 1.522 (6) angstrom] PO4 tetrahedra and SnO6 octahedra on the 3. axis, which are linked by O atoms, forming an [Sn-2(PO4)(3)] framework. The K atoms occupy the (3) over bar. axis sites and are located in the voids of this arrangement. The crystal studied was a merohedral twin with twin law (010 100 00 (1) over bar) and a component ratio of 0.580 (7):0.420 (7).
