(Bi(CO2)3)2(O2)3 crystallizes in the monoclinic P2_1/c space group. The structure consists of four trioxidane molecules inside a Bi(CO2)3 framework. In the Bi(CO2)3 framework, 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(1) and one O(2) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. In the third C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(5) and one O(6) atom. Bi(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), one O(5), one O(6), and two equivalent O(4) atoms. There are six inequivalent O sites. In the first O site, O(5) is bonded in a distorted bent 120 degrees geometry to one C(3) and one Bi(1) atom. In the second O site, O(6) is bonded in a distorted single-bond geometry to one C(3) and one Bi(1) atom. In the third O site, O(1) is bonded in a distorted bent 120 degrees geometry to one C(1) and one Bi(1) atom. In the fourth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one C(1) and one Bi(1) atom. In the fifth O site, O(3) is bonded in a distorted bent 120 degrees geometry to one C(2) and one Bi(1) atom. In the sixth O site, O(4) is bonded in a distorted single-bond geometry to one C(2) and two equivalent Bi(1) atoms.
