The compound described by CrP(HO)5 crystallizes in the orthorhombic P2_12_12_1 space group. Cr(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form CrO5 square pyramids that share corners with three equivalent P(1)HO3 tetrahedra. P(1) is bonded to one H(1), one O(1), one O(2), and one O(3) atom to form distorted PHO3 tetrahedra that share corners with three equivalent Cr(1)O5 square pyramids. There are five inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one P(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) and one O(4) atom. In the third H site, H(3) is bonded in a distorted single-bond geometry to one O(3) and one O(4) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(5) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one O(5) atom. There are five inequivalent O sites. In the first O site, O(2) is bonded in a 2-coordinate geometry to one Cr(1) and one P(1) atom. In the second O site, O(3) is bonded in a distorted trigonal planar geometry to one Cr(1), one P(1), and one H(3) atom. In the third O site, O(4) is bonded in a distorted water-like geometry to one Cr(1), one H(2), and one H(3) atom. In the fourth O site, O(5) is bonded in a distorted water-like geometry to one Cr(1), one H(4), and one H(5) atom. In the fifth O site, O(1) is bonded in a distorted trigonal planar geometry to one Cr(1), one P(1), and one H(2) atom. is represented by the CIF file [CIF]
