P(WO4)2 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(2), one O(4), one O(5), one O(8), and two equivalent O(1) atoms to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra, corners with three equivalent W(2)O6 octahedra, and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 3-18°. In the second W site, W(2) is bonded to one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom to form WO6 octahedra that share corners with three equivalent W(1)O6 octahedra and corners with three equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 3-18°. P(1) is bonded to one O(2), 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 and corners with three equivalent W(2)O6 octahedra.
