Materials Data on Sb2O5 by Materials Project

Sb2O5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Sb5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 43–54°. There are a spread of Sb–O bond distances ranging from 1.93–2.14 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Sb5+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Sb5+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to three equivalent Sb5+ atoms.
