Sr2EuSbO6 is Orthorhombic Perovskite-derived structured and crystallizes in the cubic Pn-3 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to twelve equivalent O(1) atoms to form SrO12 cuboctahedra that share faces with four equivalent Eu(1)O6 octahedra and faces with four equivalent Sb(1)O6 octahedra. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Eu(1) is bonded to six equivalent O(1) atoms to form EuO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with two equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 23°. Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra and faces with two equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 23°. O(1) is bonded in a 5-coordinate geometry to one Sr(1), two equivalent Sr(2), one Eu(1), and one Sb(1) atom.

In the first Sr site, Sr(1) is bonded to twelve equivalent O(1) atoms to form SrO12 cuboctahedra that share faces with four equivalent Eu(1)O6 octahedra and faces with four equivalent Sb(1)O6 octahedra. All Sr(1)-O(1) bond lengths are 2.98 Å. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. There are four shorter (2.56 Å) and four longer (3.06 Å) Sr(2)-O(1) bond lengths. Eu(1) is bonded to six equivalent O(1) atoms to form EuO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with two equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 23°. All Eu(1)-O(1) bond lengths are 2.30 Å. Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra and faces with two equivalent Sr(1)O12 cuboctahedra.
