The structure described by Mn2PO4Cl crystallizes in the orthorhombic Pna2_1 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(2), one O(4), two equivalent O(3), and one Cl(1) atom to form distorted MnClO5 octahedra that share corners with two equivalent Mn(1)ClO5 octahedra, corners with five equivalent Mn(2)Cl2O4 octahedra, corners with three equivalent P(1)O4 tetrahedra,  an edgeedge with one Mn(2)Cl2O4 octahedra, and  an edgeedge with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 49-70°. In the second Mn site, Mn(2) is bonded to one O(1), one O(2), one O(3), one O(4), and two equivalent Cl(1) atoms to form distorted MnCl2O4 octahedra that share corners with two equivalent Mn(2)Cl2O4 octahedra, corners with five equivalent Mn(1)ClO5 octahedra, corners with two equivalent P(1)O4 tetrahedra,  an edgeedge with one Mn(1)ClO5 octahedra, and  an edgeedge with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 49-70°. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with two equivalent Mn(2)Cl2O4 octahedra, corners with three equivalent Mn(1)ClO5 octahedra,  an edgeedge with one Mn(2)Cl2O4 octahedra, and  an edgeedge with one Mn(1)ClO5 octahedra. The corner-sharing octahedral tilt angles range from 49-57°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mn(1), one Mn(2), and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Mn(1), one Mn(2), and one P(1) atom. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Mn(2), two equivalent Mn(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Mn(1), one Mn(2), and one P(1) atom. Cl(1) is bonded in a trigonal non-coplanar geometry to one Mn(1) and two equivalent Mn(2) atoms. is represented by the CIF file [CIF]
