CoSO5 crystallizes in the monoclinic C2/c space group. Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share corners with two equivalent Co(1)O6 octahedra and corners with four equivalent S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 39°. 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 Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-48°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Co(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one S(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Co(1) and one S(1) atom.
