Materials Data on Sb5O14 by Materials Project
(Sb5O13)2O2 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional and consists of two water molecules and one Sb5O13 framework. In the Sb5O13 framework, there are three inequivalent Sb sites. In the first Sb site, Sb is bonded to six O atoms to form a mixture of edge and corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 30–46°. There are a spread of Sb–O bond distances ranging from 1.93–2.18 Å. In the second Sb site, Sb is bonded to six O atoms to form a mixture of edge and corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 44–53°. There are a spread of Sb–O bond distances ranging from 1.95–2.11 Å. In the third Sb site, Sb is bonded to six O atoms to form a mixture of edge and corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 51–53°. There are a spread of Sb–O bond distances ranging from 1.94–2.08 Å. There are seven 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 bent 150 degrees geometry to two equivalent Sb atoms. In the third O site, O is bonded in a distorted bent 120 degrees geometry to two Sb atoms. In the fourth O site, O is bonded in a trigonal planar geometry to three Sb atoms. In the fifth O site, O is bonded in a distorted trigonal planar geometry to three Sb atoms. In the sixth O site, O is bonded in a distorted bent 150 degrees geometry to two Sb atoms. In the seventh O site, O is bonded in a bent 150 degrees geometry to two Sb atoms.
