SnO2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. Sn(1) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. There are two 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 to four equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing OSn4 tetrahedra.
SnO2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. Sn(1) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. There is one shorter (2.11 Å) and two longer (2.12 Å) Sn(1)-O(1) bond lengths. There are a spread of Sn(1)-O(2) bond distances ranging from 2.04-2.43 Å. There are two 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 to four equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing OSn4 tetrahedra.
