Abstract

V2NO4F3NF crystallizes in the monoclinic Pc space group. The structure is one-dimensional and consists of two monofluoroamine molecules and two V2NO4F3 ribbons oriented in the (1, 0, 0) direction. In each V2NO4F3 ribbon, there are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded in a 5-coordinate geometry to three O2- and two F1- atoms. There are a spread of V–O bond distances ranging from 1.61–1.86 Å. There is one shorter (1.80 Å) and one longer (2.12 Å) V–F bond length. In the second V5+ site, V5+ is bonded in a distorted trigonal bipyramidal geometry to three O2- and two F1- atoms. There are a spread of V–O bond distances ranging from 1.77–2.40 Å. There is one shorter (1.79 Å) and one longer (1.92 Å) V–F bond length. N1+ is bonded in a single-bond geometry to one O2- atom. The N–O bond length is 1.16 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and one N1+ atom. In the third O2- site, O2- is bonded in a water-like geometry to two V5+ atoms. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two V5+ atoms. There are three 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 an L-shaped geometry to two V5+ atoms.
