MnOSO4 crystallizes in the triclinic P-1 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form MnO6 octahedra that share corners with two equivalent Mn(2)O6 octahedra and corners with four equivalent S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 41°. In the second Mn site, Mn(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(5) atoms to form MnO6 octahedra that share corners with two equivalent Mn(1)O6 octahedra and corners with four equivalent S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 41°. S(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form SO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra and corners with two equivalent Mn(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-51°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Mn(1) and one Mn(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Mn(2) and one S(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Mn(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Mn(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Mn(2) and one S(1) atom.
