BePH3O5 crystallizes in the orthorhombic Pna2_1 space group. Be(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form BeO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with four equivalent Be(1)O4 tetrahedra. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. In the third H site, H(3) is bonded in a linear geometry to one O(1) and one O(4) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to one H(1), one H(2), and one H(3) atom. In the second O site, O(2) is bonded in a linear geometry to one Be(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Be(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Be(1), one P(1), and one H(3) atom. In the fifth O site, O(5) is bonded in a linear geometry to one Be(1) and one P(1) atom.
