The material structure described by Mn2P3O10 crystallizes in the monoclinic P2_1/m space group. Mn(1) is bonded to one O(1), one O(3), one O(5), one O(7), and two equivalent O(2) atoms to form distorted MnO6 octahedra that share  a cornercorner with one P(1)O4 tetrahedra, corners with two equivalent P(3)O4 tetrahedra, corners with three equivalent P(2)O4 tetrahedra, and edges with two equivalent Mn(1)O6 octahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(4), one O(6), and two equivalent O(1) atoms 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 are 27°. In the second P site, P(2) is bonded to one O(3), one O(6), and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with six equivalent Mn(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 49-55°. In the third P site, P(3) is bonded to one O(4), one O(7), and two equivalent O(5) atoms to form PO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 51-52°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Mn(1) and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Mn(1) and one P(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Mn(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one P(1) and one P(3) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Mn(1) and one P(3) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the seventh O site, O(7) is bonded in a distorted trigonal planar geometry to two equivalent Mn(1) and one P(3) atom. is represented by the CIF file [CIF]
