Ca2LaSbO6 crystallizes in the cubic Pn-3 space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a q6 geometry to twelve equivalent O(1) atoms. In the second Ca site, Ca(2) is bonded in a 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 Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 34°. Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent La(1)O6 octahedra. The corner-sharing octahedral tilt angles are 34°. O(1) is bonded in a 3-coordinate geometry to one Ca(1), one Ca(2), one La(1), and one Sb(1) atom.
