Sr2LuNbO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Lu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form LuO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 23-24°. Nb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NbO6 octahedra that share corners with six equivalent Lu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 23-24°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Lu(1), and one Nb(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Lu(1), and one Nb(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to three equivalent Sr(1), one Lu(1), and one Nb(1) atom.
