Materials Data on MnSe3O8 by Materials Project

Abstract

MnSe3O8 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mn2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 1.90–2.00 Å. There are three inequivalent Se+4.67+ sites. In the first Se+4.67+ site, Se+4.67+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.70–1.84 Å. In the second Se+4.67+ site, Se+4.67+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.72 Å) and one longer (1.83 Å) Se–O bond length. In the third Se+4.67+ site, Se+4.67+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.66–1.81 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one Se+4.67+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one Se+4.67+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Se+4.67+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two Se+4.67+ atoms. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one Se+4.67+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mn2+ and one Se+4.67+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one Se+4.67+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one Se+4.67+ atom.
