In the fourth Se site, Se(4) is bonded in a 3-coordinate geometry to one Re(1), one Re(2), and one Re(3) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one K(1) and one Re(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Re(2) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one K(2) and one Re(3) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one Re(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one O(6) and one O(7) atom. In the sixth O site, O(6) is bonded in a trigonal non-coplanar geometry to two equivalent K(2) and one O(5) atom. In the seventh O site, O(7) is bonded in a distorted see-saw-like geometry to one K(2), two equivalent K(1), and one O(5) atom. is represented by the CIF file [CIF]
