The material described by V(PO3)4 crystallizes in the monoclinic C2/c space group. V(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms to form VO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra and corners with four equivalent P(1)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 corners with two equivalent V(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 39-42°. In the second P site, P(2) is bonded to one O(2), one O(4), one O(6), and one O(7) atom to form PO4 tetrahedra that share  a cornercorner with one V(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 46°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one V(1) and one P(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 150 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 V(1) and one P(1) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one P(2) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to two equivalent P(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
