The material described by CrSn(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 distorted CrO6 octahedra that share corners with four equivalent Sn(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 49-52°. Sn(1) is bonded to one O(2), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form SnO6 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 49-52°. 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 Sn(1)O6 octahedra, corners with three equivalent Cr(1)O6 octahedra, and  an edgeedge with one Sn(1)O6 octahedra.
