Materials Data on VF5 by Materials Project

Abstract

VF5 crystallizes in the monoclinic P2_1/c 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 41°. There is four shorter (1.77 Å) and two longer (1.97 Å) V–F bond length. There are five 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 single-bond geometry to one V5+ atom. The F–V bond length is 1.77 Å. In the fourth F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent V5+ atoms. In the fifth F1- site, F1- is bonded in a single-bond geometry to one V5+ atom. The F–V bond length is 1.77 Å.
