FeSO5 crystallizes in the monoclinic C2/c space group. Fe(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form FeO6 octahedra that share corners with two equivalent Fe(1)O6 octahedra and corners with four equivalent S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 34°. S(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with four equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-39°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Fe(1) and one S(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Fe(1) and one S(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent Fe(1) atoms.
