The compound described by SrCaLaBiO6 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 to two equivalent O(1) and four equivalent O(2) atoms to form CaO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-37°. La(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Bi(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form BiO6 octahedra that share corners with six equivalent Ca(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-37°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), one Ca(1), two equivalent La(1), and one Bi(1) atom to form distorted OSr2CaLa2Bi octahedra that share corners with six equivalent O(1)Sr2CaLa2Bi octahedra, corners with eight equivalent O(2)SrCaLaBi tetrahedra, edges with four equivalent O(1)Sr2CaLa2Bi octahedra, and edges with eight equivalent O(2)SrCaLaBi tetrahedra. The corner-sharing octahedral tilt angles range from 0-2°. In the second O site, O(2) is bonded to one Sr(1), one Ca(1), one La(1), and one Bi(1) atom to form distorted OSrCaLaBi tetrahedra that share corners with four equivalent O(1)Sr2CaLa2Bi octahedra, corners with ten equivalent O(2)SrCaLaBi tetrahedra, edges with four equivalent O(1)Sr2CaLa2Bi octahedra, and  an edgeedge with one O(2)SrCaLaBi tetrahedra. The corner-sharing octahedral tilt angles range from 65-69°. is represented by the CIF card [CIF]
