Materials Data on MgSe2O5 by Materials Project
MgSe2O5 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Mg2+ is bonded to six O2- atoms to form edge-sharing MgO6 octahedra. There are two shorter (2.12 Å) and four longer (2.13 Å) Mg–O bond lengths. Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.69–1.87 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Se4+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Mg2+ and one Se4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mg2+ and one Se4+ atom.
