The structure described by Tl2SnO3 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(3) atoms. In the second Tl site, Tl(2) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(3) atoms. Sn(1) is bonded to one O(3), two equivalent O(2), and three equivalent O(1) atoms to form edge-sharing SnO6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sn(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Tl(1), one Tl(2), and two equivalent Sn(1) atoms. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent Tl(1), two equivalent Tl(2), and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
