The crystal structure described by SnO2 is Hydrophilite-like structured and crystallizes in the orthorhombic Pnma space group. 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 a mixture of corner and edge-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 50-55°. In the second Sn site, Sn(2) is bonded to one O(2), two equivalent O(4), 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 50-55°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sn(2) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Sn(2) 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 trigonal planar geometry to one Sn(1) and two equivalent Sn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
