The compound described by SrEuCeSbO6 crystallizes in the tetragonal P-4n2 space group. Sr(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Eu(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Ce(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CeO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-32°. Sb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with six equivalent Ce(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-32°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), two equivalent Eu(1), one Ce(1), and one Sb(1) atom to form distorted OSr2CeEu2Sb octahedra that share corners with six equivalent O(1)Sr2CeEu2Sb octahedra, corners with eight equivalent O(2)SrCeEuSb tetrahedra, edges with four equivalent O(1)Sr2CeEu2Sb octahedra, and edges with eight equivalent O(2)SrCeEuSb tetrahedra. The corner-sharing octahedral tilt angles range from 0-3°. In the second O site, O(2) is bonded to one Sr(1), one Eu(1), one Ce(1), and one Sb(1) atom to form distorted OSrCeEuSb tetrahedra that share corners with four equivalent O(1)Sr2CeEu2Sb octahedra, corners with ten equivalent O(2)SrCeEuSb tetrahedra, edges with four equivalent O(1)Sr2CeEu2Sb octahedra, and  an edgeedge with one O(2)SrCeEuSb tetrahedra. The corner-sharing octahedral tilt angles range from 66-67°. is represented by the CIF file [CIF]
