The material structure described by SrCaEuSbO6 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. Ca(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 to two equivalent O(1) and four equivalent O(2) atoms to form EuO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-34°. 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 Eu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-34°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), two equivalent Ca(1), one Eu(1), and one Sb(1) atom to form distorted OSr2Ca2EuSb octahedra that share corners with six equivalent O(1)Sr2Ca2EuSb octahedra, corners with eight equivalent O(2)SrCaEuSb tetrahedra, edges with four equivalent O(1)Sr2Ca2EuSb octahedra, and edges with eight equivalent O(2)SrCaEuSb tetrahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the second O site, O(2) is bonded to one Sr(1), one Ca(1), one Eu(1), and one Sb(1) atom to form distorted OSrCaEuSb tetrahedra that share corners with four equivalent O(1)Sr2Ca2EuSb octahedra, corners with ten equivalent O(2)SrCaEuSb tetrahedra, edges with four equivalent O(1)Sr2Ca2EuSb octahedra, and  an edgeedge with one O(2)SrCaEuSb tetrahedra. The corner-sharing octahedral tilt angles range from 65-68°. is represented by the CIF card [CIF]
