Li2WCPO7 crystallizes in the monoclinic P2_1/m space group. Li(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. W(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form WO6 octahedra that share corners with four equivalent P(1)O4 tetrahedra. C(1) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(6) atom. P(1) is bonded to one O(4), one O(5), and two equivalent O(1) atoms to form PO4 tetrahedra that share corners with four equivalent W(1)O6 octahedra.
