MgSO4 crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MgO6 octahedra that share corners with six equivalent S(1)O4 tetrahedra and edges with two equivalent Mg(1)O6 octahedra. S(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form SO4 tetrahedra that share corners with six equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-53°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Mg(1) and one S(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent Mg(1) and one S(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Mg(1) and one S(1) atom.
