The crystal structure described by W2P3O13 crystallizes in the triclinic P-1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(10), one O(12), one O(5), one O(8), and one O(9) atom to form distorted WO6 octahedra that share  a cornercorner with one P(1)O4 tetrahedra,  a cornercorner with one P(2)O4 tetrahedra, and corners with three equivalent P(3)O4 tetrahedra. In the second W site, W(2) is bonded to one O(11), one O(13), one O(2), one O(3), one O(4), and one O(6) atom to form distorted WO6 octahedra that share  a cornercorner with one P(3)O4 tetrahedra, corners with two equivalent P(1)O4 tetrahedra, and corners with two equivalent P(2)O4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(3), one O(6), and one O(7) atom to form PO4 tetrahedra that share  a cornercorner with one W(1)O6 octahedra, corners with two equivalent W(2)O6 octahedra, and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 7-48°. In the second P site, P(2) is bonded to one O(10), one O(13), one O(2), and one O(7) atom to form PO4 tetrahedra that share  a cornercorner with one W(1)O6 octahedra, corners with two equivalent W(2)O6 octahedra, and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 7-47°. In the third P site, P(3) is bonded to one O(12), one O(4), one O(5), and one O(9) atom to form PO4 tetrahedra that share  a cornercorner with one W(2)O6 octahedra and corners with three equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-37°. There are thirteen inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one W(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one W(2) and one P(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one W(2) and one P(1) atom.

In the eighth O site, O(8) is bonded in a single-bond geometry to one W(1) atom. In the ninth O site, O(9) is bonded in a bent 150 degrees geometry to one W(1) and one P(3) atom. In the tenth O site, O(10) is bonded in a distorted linear geometry to one W(1) and one P(2) atom. In the eleventh O site, O(11) is bonded in a single-bond geometry to one W(2) atom. In the twelfth O site, O(12) is bonded in a bent 150 degrees geometry to one W(1) and one P(3) atom. In the thirteenth O site, O(13) is bonded in a bent 150 degrees geometry to one W(2) and one P(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
