The structure described by SnO2 is Baddeleyite-like structured and crystallizes in the orthorhombic Pbca space group. Sn(1) is bonded to three equivalent O(1) and four equivalent O(2) atoms to form a mixture of distorted edge and corner-sharing SnO7 pentagonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to three equivalent Sn(1) atoms. In the second O site, O(2) is bonded to four equivalent Sn(1) atoms to form a mixture of edge and corner-sharing OSn4 tetrahedra. is represented by the CIF file [CIF]
