CrPO5 crystallizes in the orthorhombic Pnma space group. Cr(1) is bonded to one O(2), one O(3), one O(4), and two equivalent O(1) atoms to form distorted CrO5 trigonal bipyramids that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(3), one O(4), and two equivalent O(1) atoms to form PO4 tetrahedra that share corners with four equivalent Cr(1)O5 trigonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Cr(1) and one P(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Cr(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 bent 150 degrees geometry to one Cr(1) and one P(1) atom.
