SbO2 crystallizes in the orthorhombic Imma space group. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing SbO6 octahedra. In the second Sb site, Sb(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted edge-sharing SbO6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Sb(2) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Sb(1) and two equivalent Sb(2) atoms.
SbO2 crystallizes in the orthorhombic Imma space group. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing SbO6 octahedra. Both Sb(1)-O(2) bond lengths are 1.99 Å. All Sb(1)-O(1) bond lengths are 2.07 Å. In the second Sb site, Sb(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted edge-sharing SbO6 octahedra. Both Sb(2)-O(1) bond lengths are 2.40 Å. All Sb(2)-O(2) bond lengths are 2.34 Å. There are two inequivalent O sites.
