Materials Data on GaH8N2OF5 by Materials Project

Abstract

GaN2H8OF5 crystallizes in the orthorhombic Pbca space group. The structure is two-dimensional and consists of two GaN2H8OF5 sheets oriented in the (0, 0, 1) direction. Ga3+ is bonded in an octahedral geometry to one O2- and five F1- atoms. The Ga–O bond length is 2.01 Å. There are a spread of Ga–F bond distances ranging from 1.90–1.96 Å. There are two inequivalent N2- sites. In the first N2- site, N2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There are a spread of N–H bond distances ranging from 1.05–1.07 Å. In the second N2- site, N2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There is two shorter (1.05 Å) and one longer (1.08 Å) N–H bond length. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the second H1+ site, H1+ is bonded in a distorted linear geometry to one O2- and one F1- atom. The H–O bond length is 1.00 Å. The H–F bond length is 1.59 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the fifth H1+ site, H1+ is bonded in a distorted linear geometry to one N2- and one F1- atom. The H–F bond length is 1.52 Å. In the sixth H1+ site, H1+ is bonded in a linear geometry to one N2- and one F1- atom. The H–F bond length is 1.51 Å. In the seventh H1+ site, H1+ is bonded in a distorted single-bond geometry to one N2- and one F1- atom. The H–F bond length is 1.62 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- and one F1- atom. The H–O bond length is 1.00 Å. The H–F bond length is 1.68 Å. O2- is bonded in a distorted water-like geometry to one Ga3+ and two H1+ atoms. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a 3-coordinate geometry to one Ga3+ and two H1+ atoms. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to one Ga3+ and one H1+ atom. In the third F1- site, F1- is bonded in a 2-coordinate geometry to one Ga3+ and one H1+ atom. In the fourth F1- site, F1- is bonded in a distorted single-bond geometry to one Ga3+ atom. In the fifth F1- site, F1- is bonded in a water-like geometry to one Ga3+ and one H1+ atom.
