Title: Materials Data on Ba2CrN3 by Materials Project

Abstract

Ba2CrN3 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 7-coordinate geometry to seven N3- atoms. There are a spread of Ba–N bond distances ranging from 2.88–3.15 Å. In the second Ba2+ site, Ba2+ is bonded to seven N3- atoms to form distorted BaN7 pentagonal bipyramids that share corners with four equivalent BaN7 pentagonal bipyramids, a cornercorner with one CrN4 tetrahedra, edges with three equivalent BaN7 pentagonal bipyramids, and edges with four equivalent CrN4 tetrahedra. There are a spread of Ba–N bond distances ranging from 2.83–2.95 Å. Cr5+ is bonded to four N3- atoms to form CrN4 tetrahedra that share a cornercorner with one BaN7 pentagonal bipyramid, corners with two equivalent CrN4 tetrahedra, and edges with four equivalent BaN7 pentagonal bipyramids. There are a spread of Cr–N bond distances ranging from 1.75–1.83 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a 2-coordinate geometry to four Ba2+ and two equivalent Cr5+ atoms. In the second N3- site, N3- is bonded in a distorted single-bond geometry to five Ba2+ and one Cr5+ atom.
