Materials Data on SbO2 by Materials Project

SbO2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Sb sites. In the first Sb site, Sb is bonded in a distorted rectangular see-saw-like geometry to four equivalent O atoms. There are two shorter (2.06 Å) and two longer (2.24 Å) Sb–O bond lengths. In the second Sb site, Sb is bonded to six O atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are a spread of Sb–O bond distances ranging from 2.00–2.04 Å. There are two inequivalent O sites. In the first O site, O is bonded in a trigonal planar geometry to three Sb atoms. In the second O site, O is bonded in a distorted bent 120 degrees geometry to two equivalent Sb atoms.
