The structure described by SrCaEuBiO6 crystallizes in the tetragonal P42_12 space group. Sr(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(2) and four equivalent O(3) atoms. Ca(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(3) atoms. Eu(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form EuO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-35°. Bi(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent Eu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-35°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Ca(1), one Eu(1), and one Bi(1) atom. In the second O site, O(2) is bonded to four equivalent Sr(1), one Eu(1), and one Bi(1) atom to form distorted OSr4EuBi octahedra that share corners with four equivalent O(2)Sr4EuBi octahedra, corners with eight equivalent O(3)SrCaEuBi tetrahedra, edges with four equivalent O(2)Sr4EuBi octahedra, and edges with eight equivalent O(3)SrCaEuBi tetrahedra. The corner-sharing octahedral tilt angles are 3°. In the third O site, O(3) is bonded to one Sr(1), one Ca(1), one Eu(1), and one Bi(1) atom to form distorted OSrCaEuBi tetrahedra that share corners with two equivalent O(2)Sr4EuBi octahedra, corners with ten equivalent O(3)SrCaEuBi tetrahedra, edges with two equivalent O(2)Sr4EuBi octahedra, and  an edgeedge with one O(3)SrCaEuBi tetrahedra.
