Materials Data on Sb6S2O15 by Materials Project
Sb6O7(SO4)2 crystallizes in the orthorhombic Ccc2 space group. The structure is three-dimensional. there are three inequivalent Sb+4.33+ sites. In the first Sb+4.33+ site, Sb+4.33+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.02–2.40 Å. In the second Sb+4.33+ site, Sb+4.33+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.05–2.28 Å. In the third Sb+4.33+ site, Sb+4.33+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.04–2.34 Å. S2+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.47–1.54 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Sb+4.33+ and one S2+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sb+4.33+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Sb+4.33+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Sb+4.33+ atoms. In the sixth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Sb+4.33+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to three Sb+4.33+ atoms. In the eighth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom.
