The crystal structure described by KSmWO6Sn crystallizes in the tetragonal P4_2/mmc space group. The structure consists of two 7440-31-5 atoms inside a KSmWO6 framework. In the KSmWO6 framework, K(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form KO12 cuboctahedra that share corners with four equivalent K(1)O12 cuboctahedra, faces with two equivalent K(1)O12 cuboctahedra, faces with four equivalent Sm(1)O6 octahedra, and faces with four equivalent W(1)O6 octahedra. Sm(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SmO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with four equivalent K(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-3°. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form WO6 octahedra that share corners with six equivalent Sm(1)O6 octahedra and faces with four equivalent K(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-3°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to two equivalent K(1), one Sm(1), and one W(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent K(1), one Sm(1), and one W(1) atom. is represented by the CIF file [CIF]
