The Materials Project

K2Sn2O3 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a hexagonal planar geometry to six equivalent O2- atoms. All K–O bond lengths are 3.07 Å. In the second K1+ site, K1+ is bonded in a hexagonal planar geometry to six equivalent O2- atoms. All K–O bond lengths are 2.99 Å. Sn2+ is bonded in a distorted T-shaped geometry to three equivalent O2- atoms. All Sn–O bond lengths are 2.07 Å. O2- is bonded to four K1+ and two equivalent Sn2+ atoms to form a mixture of distorted corner and face-sharing OK4Sn2 octahedra. The corner-sharing octahedra tilt angles range from 0–62°.
