The crystal structure described by Ti(PO3)4 crystallizes in the monoclinic C2/c space group. Ti(1) is bonded to two equivalent O(2), two equivalent O(5), and two equivalent O(6) atoms to form TiO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with four equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share  a cornercorner with one Ti(1)O6 octahedra and corners with two equivalent P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 30°. In the second P site, P(2) is bonded to one O(2), one O(3), one O(4), and one O(6) atom to form PO4 tetrahedra that share corners with two equivalent Ti(1)O6 octahedra and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 18-39°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ti(1) and one P(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Ti(1) and one P(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Ti(1) and one P(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
