Materials Data on Sr2LuNbO6 by Materials Project

Sr2LuNbO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.54–3.19 Å. Lu3+ is bonded to six O2- atoms to form LuO6 octahedra that share corners with six equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 23–24°. All Lu–O bond lengths are 2.20 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six equivalent LuO6 octahedra. The corner-sharing octahedra tilt angles range from 23–24°. All Nb–O bond lengths are 2.03 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+, one Lu3+, and one Nb5+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+, one Lu3+, and one Nb5+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Sr2+, one Lu3+, and one Nb5+ atom.
