The crystal structure described by Li2SnO3 is Caswellsilverite-like structured and crystallizes in the monoclinic C2/c space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form LiO6 octahedra that share corners with two equivalent Li(3)O6 octahedra, corners with two equivalent Sn(1)O6 octahedra, corners with two equivalent Sn(2)O6 octahedra, edges with two equivalent Li(3)O6 octahedra, edges with two equivalent Sn(1)O6 octahedra, edges with two equivalent Sn(2)O6 octahedra, edges with three equivalent Li(1)O6 octahedra, and edges with three equivalent Li(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 5-6°. In the second Li site, Li(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form LiO6 octahedra that share corners with two equivalent Li(3)O6 octahedra, corners with two equivalent Sn(1)O6 octahedra, corners with two equivalent Sn(2)O6 octahedra, edges with two equivalent Li(3)O6 octahedra, edges with two equivalent Sn(1)O6 octahedra, edges with two equivalent Sn(2)O6 octahedra, and edges with six equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 4-5°. In the third Li site, Li(3) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form LiO6 octahedra that share corners with two equivalent Li(2)O6 octahedra, corners with four equivalent Li(1)O6 octahedra, edges with two equivalent Li(2)O6 octahedra, edges with three equivalent Sn(1)O6 octahedra, edges with three equivalent Sn(2)O6 octahedra, and edges with four equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles are 5°. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SnO6 octahedra that share corners with two equivalent Li(2)O6 octahedra, corners with four equivalent Li(1)O6 octahedra, edges with two equivalent Li(2)O6 octahedra, edges with three equivalent Li(3)O6 octahedra, edges with three equivalent Sn(2)O6 octahedra, and edges with four equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 4-6°. In the second Sn site, Sn(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SnO6 octahedra that share corners with two equivalent Li(2)O6 octahedra, corners with four equivalent Li(1)O6 octahedra, edges with two equivalent Li(2)O6 octahedra, edges with three equivalent Li(3)O6 octahedra, edges with three equivalent Sn(1)O6 octahedra, and edges with four equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 5-6°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Li(2), one Li(3), two equivalent Li(1), one Sn(1), and one Sn(2) atom to form a mixture of edge and corner-sharing OLi4Sn2 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the second O site, O(2) is bonded to one Li(2), one Li(3), two equivalent Li(1), one Sn(1), and one Sn(2) atom to form a mixture of edge and corner-sharing OLi4Sn2 octahedra. The corner-sharing octahedral tilt angles range from 0-8°. In the third O site, O(3) is bonded to one Li(2), one Li(3), two equivalent Li(1), one Sn(1), and one Sn(2) atom to form a mixture of edge and corner-sharing OLi4Sn2 octahedra. The corner-sharing octahedral tilt angles range from 0-8°. is represented by the CIF card [CIF]
