Title: Materials Data on La2GaN3 by Materials Project

Abstract

La2GaN3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 6-coordinate geometry to six N3- atoms. There are a spread of La–N bond distances ranging from 2.44–2.80 Å. In the second La3+ site, La3+ is bonded in a 7-coordinate geometry to six N3- atoms. There are a spread of La–N bond distances ranging from 2.48–2.74 Å. Ga3+ is bonded to four N3- atoms to form corner-sharing GaN4 tetrahedra. There are a spread of Ga–N bond distances ranging from 1.93–2.01 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a 5-coordinate geometry to four La3+ and one Ga3+ atom. In the second N3- site, N3- is bonded in a 2-coordinate geometry to four La3+ and two equivalent Ga3+ atoms. In the third N3- site, N3- is bonded to four La3+ and two equivalent Ga3+ atoms to form a mixture of distorted edge and corner-sharing NLa4Ga2 octahedra. In the fourth N3- site, N3- is bonded to four La3+ and one Ga3+ atom to form distorted NLa4Ga trigonal bipyramids that share corners with three equivalent NLa4Ga2 octahedra, anmore » edgeedge with one NLa4Ga2 octahedra, and edges with two equivalent NLa4Ga trigonal bipyramids. The corner-sharing octahedra tilt angles range from 48–57°.« less
