CoSO4 crystallizes in the orthorhombic Pnma 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 six equivalent S(1)O4 tetrahedra and edges with two equivalent Co(1)O6 octahedra. S(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-53°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Co(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Co(1) and one S(1) atom.
