CdSO5 crystallizes in the monoclinic P2_1/c space group. Cd(1) is bonded to one O(1), one O(2), one O(3), one O(4), and two equivalent O(5) atoms to form CdO6 octahedra that share corners with two equivalent Cd(1)O6 octahedra and corners with four equivalent S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. S(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SO4 tetrahedra that share corners with four equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-61°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and one S(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cd(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Cd(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to two equivalent Cd(1) atoms.
