SbO2 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. In the second Sb site, Sb(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 43°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Sb(2) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and two equivalent Sb(2) atoms.
SbO2 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Both Sb(1)-O(2) bond lengths are 2.70 Å. There are two shorter (2.04 Å) and two longer (2.23 Å) Sb(1)-O(1) bond lengths. In the second Sb site, Sb(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 43°. Both Sb(2)-O(1) bond lengths are 2.02 Å. There are two shorter (1.95 Å) and two longer (1.98 Å) Sb(2)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Sb(2) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and two equivalent Sb(2) atoms.
