Materials Data on BeNF3 by Materials Project
BeF2NF crystallizes in the monoclinic Pc space group. The structure is one-dimensional and consists of four monofluoroamine molecules and two BeF2 ribbons oriented in the (0, 1, 0) direction. In each BeF2 ribbon, there are two inequivalent Be2+ sites. In the first Be2+ site, Be2+ is bonded in a trigonal planar geometry to three F1- atoms. There are a spread of Be–F bond distances ranging from 1.40–1.54 Å. In the second Be2+ site, Be2+ is bonded in a trigonal planar geometry to three F1- atoms. There are a spread of Be–F bond distances ranging from 1.41–1.54 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to two Be2+ atoms. In the second F1- site, F1- is bonded in a single-bond geometry to one Be2+ atom. In the third F1- site, F1- is bonded in a bent 150 degrees geometry to two Be2+ atoms. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Be2+ atom.
