The structure described by CdS2O7 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(5), one O(6), and one O(7) atom to form CdO6 octahedra that share corners with three equivalent S(1)O4 tetrahedra and corners with three equivalent S(2)O4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form SO4 tetrahedra that share corners with three equivalent Cd(1)O6 octahedra and  a cornercorner with one S(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 33-53°. In the second S site, S(2) is bonded to one O(3), one O(4), one O(6), and one O(7) atom to form SO4 tetrahedra that share corners with three equivalent Cd(1)O6 octahedra and  a cornercorner with one S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 42-49°. There are seven inequivalent O sites. In the first O site, O(6) is bonded in a 2-coordinate geometry to one Cd(1) and one S(2) atom. In the second O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and one S(2) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one Cd(1) and one S(1) atom. In the fourth O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Cd(1) and one S(1) atom. In the fifth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Cd(1) and one S(2) atom. In the sixth O site, O(4) is bonded in a bent 120 degrees geometry to one S(1) and one S(2) atom. In the seventh O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and one S(1) atom. is represented by the CIF card [CIF]
