In the third Bi site, Bi(3) is bonded in a 6-coordinate geometry to one O(1), one O(5), one O(6), one O(7), and two equivalent O(4) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to two equivalent O(3), two equivalent O(6), and two equivalent O(7) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 40°. In the second Sb site, Sb(2) is bonded to two equivalent O(2), two equivalent O(5), and two equivalent O(7) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 40°. There are seven inequivalent O sites. In the first O site, O(1) is bonded to one Bi(1), one Bi(3), and two equivalent Bi(2) atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Bi(1) and one Sb(2) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Bi(1) and one Sb(1) atom. In the fourth O site, O(4) is bonded to one Bi(1), one Bi(2), and two equivalent Bi(3) atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Bi(2), one Bi(3), and one Sb(2) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Bi(2), one Bi(3), and one Sb(1) atom. In the seventh O site, O(7) is bonded in a 4-coordinate geometry to one Bi(1), one Bi(3), one Sb(1), and one Sb(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
