Materials Data on MgSb2O5 by Materials Project

Abstract

MgSb2O5 is Antimony trioxide-derived structured and crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one MgSb2O5 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.00–2.72 Å. In the second Mg2+ site, Mg2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.00–2.61 Å. There are four inequivalent Sb4+ sites. In the first Sb4+ site, Sb4+ 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 1.97–2.43 Å. In the second Sb4+ site, Sb4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 1.97–2.40 Å. In the third Sb4+ site, Sb4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Sb–O bond distances ranging from 1.86–2.30 Å. In the fourth Sb4+ site, Sb4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Sb–O bond distances ranging from 1.87–2.31 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Mg2+ and two Sb4+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Mg2+ and two Sb4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Mg2+ and two equivalent Sb4+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Mg2+ and two equivalent Sb4+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Sb4+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Sb4+ atoms. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Mg2+ and one Sb4+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Mg2+ and one Sb4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mg2+ and one Sb4+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mg2+ and one Sb4+ atom.
