ZnSO5 crystallizes in the monoclinic C2/c space group. Zn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form ZnO6 octahedra that share corners with two equivalent Zn(1)O6 octahedra and corners with four equivalent S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 48°. S(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form SO4 tetrahedra that share corners with four equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-49°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Zn(1) atoms. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Zn(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one S(1) atom.
