The crystal structure described by V(PO3)3 crystallizes in the monoclinic Cc space group. V(1) is bonded to one O(1), one O(4), one O(6), one O(7), one O(8), and one O(9) atom to form VO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, and corners with two equivalent P(3)O4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(9) atom to form PO4 tetrahedra that share corners with two equivalent V(1)O6 octahedra,  a cornercorner with one P(2)O4 tetrahedra, and  a cornercorner with one P(3)O4 tetrahedra.
