The material described by SnO2 crystallizes in the orthorhombic Cmcm space group. Sn(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 0-51°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to three equivalent Sn(1) atoms. In the second O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Sn(1) atoms. In the third O site, O(3) is bonded in a square co-planar geometry to four equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
