The crystal structure described by Mn2(SO4)3 crystallizes in the monoclinic C2/c space group. Mn(1) is bonded to one O(1), one O(3), one O(5), one O(6), and two equivalent O(4) atoms to form distorted MnO6 octahedra that share corners with two equivalent S(2)O4 tetrahedra, corners with four equivalent S(1)O4 tetrahedra, and  an edgeedge with one Mn(1)O6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to one O(2), one O(3), one O(4), and one O(6) atom to form SO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-55°. In the second S site, S(2) is bonded to two equivalent O(1) and two equivalent O(5) atoms to form SO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 12-36°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Mn(1) and one S(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one S(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Mn(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to two equivalent Mn(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a linear geometry to one Mn(1) and one S(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one Mn(1) and one S(1) atom. is represented by the CIF card [CIF]
