In the fourth Bi site, Bi(4) is bonded in a 5-coordinate geometry to one O(2), one O(6), one O(7), and two equivalent O(5) atoms. There are ten inequivalent O sites. In the first O site, O(1) is bonded to one Zn(2), one Bi(3), and two equivalent Bi(2) atoms to form distorted corner-sharing OZnBi3 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to one Zn(1), one Bi(1), and one Bi(4) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Bi(2) and two equivalent Bi(1) atoms. In the fourth O site, O(4) is bonded in a trigonal non-coplanar geometry to one Bi(1) and two equivalent Bi(2) atoms. In the fifth O site, O(5) is bonded in a trigonal non-coplanar geometry to one Bi(3) and two equivalent Bi(4) atoms. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Bi(4) and two equivalent Bi(3) atoms. In the seventh O site, O(7) is bonded in a distorted trigonal planar geometry to two equivalent Zn(1) and one Bi(4) atom. In the eighth O site, O(8) is bonded in a water-like geometry to one Zn(2) and one Bi(3) atom.
