The structure described by CrMn(PO4)2 crystallizes in the monoclinic P2_1/m space group. Cr(1) is bonded to one O(1), one O(3), two equivalent O(5), and two equivalent O(6) atoms to form CrO6 octahedra that share corners with four equivalent Mn(1)O6 octahedra,  a cornercorner with one P(2)O4 tetrahedra, corners with three equivalent P(1)O4 tetrahedra, and  an edgeedge with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 50-51°. Mn(1) is bonded to one O(2), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form distorted MnO6 octahedra that share corners with four equivalent Cr(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, corners with three equivalent P(2)O4 tetrahedra, and  an edgeedge with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 50-51°. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), and two equivalent O(5) atoms to form PO4 tetrahedra that share  a cornercorner with one Mn(1)O6 octahedra, corners with three equivalent Cr(1)O6 octahedra, and  an edgeedge with one Mn(1)O6 octahedra.

In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Cr(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Mn(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Cr(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Mn(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Cr(1), one Mn(1), and one P(1) atom.
