VO(PO3)2 crystallizes in the triclinic P-1 space group. V(1) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), and one O(7) atom to form VO6 octahedra that share corners with three equivalent P(1)O4 tetrahedra and corners with three 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(4), one O(5), and one O(6) atom to form PO4 tetrahedra that share corners with three equivalent V(1)O6 octahedra and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 17-50°. In the second P site, P(2) is bonded to one O(2), one O(3), one O(4), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent V(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 28-40°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one V(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 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(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one P(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a linear geometry to one V(1) and one P(1) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one V(1) and one P(1) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one V(1) and one P(2) atom.
