BaSrBiSbO6 is Orthorhombic Perovskite-derived structured and crystallizes in the trigonal R3 space group. Ba(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. Sr(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. Bi(1) is bonded to three equivalent O(1) and three 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 20-27°. Sb(1) is bonded to three equivalent O(1) and three 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 20-27°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Sr(1), one Bi(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Ba(1), one Sr(1), one Bi(1), and one Sb(1) atom.
