The material structure described by (CdSO4)3(O2)4 crystallizes in the monoclinic C2/c space group. The structure consists of sixteen hydrogen peroxide molecules inside a CdSO4 framework. In the CdSO4 framework, there are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(3) and two equivalent O(5) atoms. In the second Cd site, Cd(2) is bonded to one O(1), one O(2), one O(4), and one O(6) atom to form distorted CdO4 tetrahedra that share corners with two equivalent S(1)O4 tetrahedra and corners with two equivalent S(2)O4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with four equivalent Cd(2)O4 tetrahedra. In the second S site, S(2) is bonded to one O(3), one O(4), one O(5), and one O(6) atom to form SO4 tetrahedra that share corners with two equivalent Cd(2)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(3) is bonded in a bent 150 degrees geometry to one Cd(1) and one S(2) atom. In the second O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Cd(2) and one S(2) atom. In the third O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Cd(1) and one S(2) atom. In the fourth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Cd(2) and one S(2) atom. In the fifth O site, O(1) is bonded in a bent 150 degrees geometry to one Cd(2) and one S(1) atom. In the sixth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Cd(2) and one S(1) atom. is represented by the CIF card [CIF]
