CrPO4 crystallizes in the orthorhombic Pnma space group. Cr(1) is bonded to one O(1), one O(3), and four equivalent O(2) atoms to form CrO6 octahedra that share corners with four equivalent Cr(1)O6 octahedra, corners with four equivalent P(1)O4 tetrahedra, and  an edgeedge with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 49°. P(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Cr(1)O6 octahedra and  an edgeedge with one Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-58°. There are three inequivalent O sites. 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 distorted trigonal planar geometry to two equivalent Cr(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(1) atom.

The corner-sharing octahedral tilt angles are 49°. The Cr(1)-O(1) bond length is 1.93 Å. The Cr(1)-O(3) bond length is 1.97 Å. There are two shorter (2.03 Å) and two longer (2.07 Å) Cr(1)-O(2) bond lengths. P(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Cr(1)O6 octahedra and  an edgeedge with one Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-58°. The P(1)-O(1) bond length is 1.52 Å. The P(1)-O(3) bond length is 1.52 Å. Both P(1)-O(2) bond lengths are 1.60 Å. There are three inequivalent O sites. 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.
