Title: Materials Data on Ba2MgO3 by Materials Project

Abstract

Ba2MgO3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to seven O2- atoms to form distorted BaO7 pentagonal bipyramids that share corners with four BaO7 pentagonal bipyramids, a cornercorner with one MgO4 tetrahedra, edges with three equivalent BaO7 pentagonal bipyramids, and edges with four MgO4 tetrahedra. There are a spread of Ba–O bond distances ranging from 2.72–3.22 Å. In the second Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to seven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.66–3.42 Å. In the third Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six O2- atoms.
