U(1) is bonded in a distorted pentagonal bipyramidal geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(7), and one O(8) atom. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(5) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(4) and one O(6) atom. In the third C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(7) and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(4) is bonded in a 3-coordinate geometry to one Rb(1), one U(1), and one C(2) atom.
