Materials Data on VW3 by Materials Project
VW3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. V is bonded in a distorted body-centered cubic geometry to fourteen W atoms. There are eight shorter (2.72 Å) and six longer (3.14 Å) V–W bond lengths. There are two inequivalent W sites. In the first W site, W is bonded to four equivalent V and four equivalent W atoms to form a mixture of distorted edge, face, and corner-sharing WV4W4 tetrahedra. All W–W bond lengths are 2.72 Å. In the second W site, W is bonded in a 8-coordinate geometry to six equivalent V and eight equivalent W atoms.
