TaW3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Ta(1) is bonded in a distorted body-centered cubic geometry to six equivalent W(2) and eight equivalent W(1) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to four equivalent Ta(1) and four equivalent W(2) atoms to form a mixture of distorted edge, corner, and face-sharing WTa4W4 tetrahedra. In the second W site, W(2) is bonded in a 14-coordinate geometry to six equivalent Ta(1) and eight equivalent W(1) atoms.
