PHTeO5 crystallizes in the triclinic P-1 space group. 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 two equivalent Te(1)O6 octahedra and corners with two equivalent Te(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-49°. H(1) is bonded in a single-bond geometry to one O(1) and one O(2) atom. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TeO6 octahedra that share corners with two equivalent Te(2)O6 octahedra and corners with four equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. In the second Te site, Te(2) is bonded to two equivalent O(1), two equivalent O(4), and two equivalent O(5) atoms to form TeO6 octahedra that share corners with two equivalent Te(1)O6 octahedra and corners with four equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one H(1), one Te(1), and one Te(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one P(1), one H(1), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one P(1) and one Te(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one P(1) and one Te(2) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one P(1) and one Te(2) atom.
