Materials Data on VF5 by Materials Project

Abstract

VF5 crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of two VF5 ribbons oriented in the (1, 0, 0) direction. V5+ is bonded to six F1- atoms to form corner-sharing VF6 octahedra. The corner-sharing octahedral tilt angles are 26°. There are a spread of V–F bond distances ranging from 1.73–2.03 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one V5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one V5+ atom. In the third F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent V5+ atoms. In the fourth F1- site, F1- is bonded in a single-bond geometry to one V5+ atom.
