The material structure described by V(PO3)4 crystallizes in the monoclinic P2_1 space group. V(1) is bonded to one O(12), one O(2), one O(4), one O(5), one O(7), and one O(8) atom to form VO6 octahedra that share  a cornercorner with one P(1)O4 tetrahedra,  a cornercorner with one P(4)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, and corners with two equivalent P(3)O4 tetrahedra. There are four inequivalent P sites.
