Sr2LaNbO6 crystallizes in the cubic Pn-3 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a q6 geometry to twelve equivalent O(1) atoms. In the second Sr site, Sr(2) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. La(1) is bonded to six equivalent O(1) atoms to form LaO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 28°. Nb(1) is bonded to six equivalent O(1) atoms to form NbO6 octahedra that share corners with six equivalent La(1)O6 octahedra. The corner-sharing octahedral tilt angles are 28°. O(1) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), one La(1), and one Nb(1) atom.
