The material structure described by CrPO4 crystallizes in the orthorhombic Pbca space group. Cr(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form distorted CrO6 octahedra that share corners with two equivalent Cr(1)O6 octahedra, corners with six equivalent P(1)O4 tetrahedra, and  an edgeedge with one Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 66°. 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 six equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-62°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Cr(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Cr(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Cr(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent Cr(1) and one P(1) atom. is represented by the CIF card [CIF]
