The structure described by Li3WCPO7 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to one O(3), one O(4), one O(5), and one O(6) atom. In the second Li site, Li(2) is bonded in a 4-coordinate geometry to one O(2), one O(6), and two equivalent O(4) atoms. W(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), and two equivalent O(4) atoms. 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 in a tetrahedral geometry to one O(1), one O(5), and two equivalent O(4) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one W(1) and one P(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Li(2), one W(1), and one C(1) atom. In the third O site, O(3) is bonded in a distorted trigonal pyramidal geometry to two equivalent Li(1), one W(1), and one C(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Li(1), one Li(2), one W(1), and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one P(1) atom. In the sixth O site, O(6) is bonded in a distorted rectangular see-saw-like geometry to one Li(2), two equivalent Li(1), and one C(1) atom. is represented by the CIF card [CIF]
