The material structure described by Mg(SnO2)2 crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to one O(4), two equivalent O(2), and three equivalent O(3) atoms to form edge-sharing SnO6 octahedra. In the second Sn site, Sn(2) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Sn(2) atoms. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mg(1) and two equivalent Sn(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sn(1) atoms. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to two equivalent Mg(1), one Sn(1), and two equivalent Sn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
