Materials Data on K3V by Materials Project
VK3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded to four equivalent K and four equivalent V atoms to form a mixture of distorted corner, edge, and face-sharing KK4V4 tetrahedra. All K–K bond lengths are 3.99 Å. All K–V bond lengths are 3.99 Å. In the second K site, K is bonded in a body-centered cubic geometry to eight equivalent K atoms. V is bonded in a body-centered cubic geometry to eight equivalent K atoms.
