The material structure described by Ca2BiSbO6 crystallizes in the tetragonal P4/mnc space group. Ca(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 Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-39°. 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 Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-39°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ca(1), one Bi(1), and one Sb(1) atom to form distorted OCa4BiSb octahedra that share corners with six equivalent O(1)Ca4BiSb octahedra, corners with eight equivalent O(2)Ca2BiSb tetrahedra, edges with four equivalent O(1)Ca4BiSb octahedra, and edges with eight equivalent O(2)Ca2BiSb tetrahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the second O site, O(2) is bonded to two equivalent Ca(1), one Bi(1), and one Sb(1) atom to form distorted OCa2BiSb tetrahedra that share corners with four equivalent O(1)Ca4BiSb octahedra, corners with ten equivalent O(2)Ca2BiSb tetrahedra, edges with four equivalent O(1)Ca4BiSb octahedra, and  an edgeedge with one O(2)Ca2BiSb tetrahedra. The corner-sharing octahedral tilt angles range from 67-69°. is represented by the CIF card [CIF]
