BaSrLaBiO6 crystallizes in the tetragonal I-4 space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Sr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SrO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-40°. La(1) is bonded in a 8-coordinate 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 Sr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-40°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to two equivalent Ba(1), one Sr(1), two equivalent La(1), and one Bi(1) atom. In the second O site, O(2) is bonded to one Ba(1), one Sr(1), one La(1), and one Bi(1) atom to form a mixture of distorted corner and edge-sharing OBaSrLaBi tetrahedra.
