Materials Data on VF4 by Materials Project

Abstract

VF4 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two VF4 ribbons oriented in the (1, 0, 0) direction. V4+ is bonded to six F1- atoms to form edge-sharing VF6 octahedra. There are a spread of V–F bond distances ranging from 1.76–2.04 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a water-like geometry to two equivalent V4+ atoms. In the second F1- site, F1- is bonded in a single-bond geometry to one V4+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one V4+ atom. In the fourth F1- site, F1- is bonded in a water-like geometry to two equivalent V4+ atoms.
