Materials Data on VF4 by Materials Project

Abstract

VF4 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one VF4 sheet oriented in the (0, 0, 1) direction. V4+ is bonded to six F1- atoms to form corner-sharing VF6 octahedra. The corner-sharing octahedra tilt angles range from 29–33°. There are a spread of V–F bond distances ranging from 1.75–2.01 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent V4+ atoms. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent V4+ atoms. 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 single-bond geometry to one V4+ atom.
