Materials Data on SbO2 by Materials Project

Abstract

SbO2 crystallizes in the orthorhombic Pnna space group. The structure is three-dimensional. there are two inequivalent Sb sites. In the first Sb site, Sb is bonded in a 4-coordinate geometry to four O atoms. There are two shorter (2.05 Å) and two longer (2.37 Å) Sb–O bond lengths. In the second Sb site, Sb is bonded to six O atoms to form distorted edge-sharing SbO6 octahedra. There are a spread of Sb–O bond distances ranging from 1.96–2.14 Å. There are two inequivalent O sites. In the first O site, O is bonded in a water-like geometry to two Sb atoms. In the second O site, O is bonded in a distorted trigonal non-coplanar geometry to three Sb atoms.
