The material structure described by Mn(PO3)3 crystallizes in the monoclinic Cc space group. Mn(1) is bonded to one O(2), one O(3), one O(4), one O(5), one O(8), and one O(9) atom to form MnO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, and corners with two equivalent P(3)O4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(6) atom to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra,  a cornercorner with one P(2)O4 tetrahedra, and  a cornercorner with one P(3)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 29-49°. In the second P site, P(2) is bonded to one O(1), one O(4), one O(5), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(3)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 32-45°. In the third P site, P(3) is bonded to one O(6), one O(7), one O(8), and one O(9) atom to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 38-46°. There are nine inequivalent O sites. In the first O site, O(9) is bonded in a distorted bent 120 degrees geometry to one Mn(1) and one P(3) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the third O site, O(2) is bonded in a bent 150 degrees geometry to one Mn(1) and one P(1) atom.
