WCu3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. W(1) is bonded in a distorted body-centered cubic geometry to six equivalent Cu(2) and eight equivalent Cu(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to four equivalent W(1) and four equivalent Cu(2) atoms to form a mixture of distorted corner, edge, and face-sharing CuCu4W4 tetrahedra. In the second Cu site, Cu(2) is bonded in a 14-coordinate geometry to six equivalent W(1) and eight equivalent Cu(1) atoms.
