Materials Data on GaH3NF3 by Materials Project

Abstract

GaNH3F3 crystallizes in the orthorhombic Aem2 space group. The structure is two-dimensional and consists of two GaNH3F3 sheets oriented in the (0, 1, 0) direction. Ga3+ is bonded to one N3- and five F1- atoms to form corner-sharing GaNF5 octahedra. The corner-sharing octahedra tilt angles range from 4–9°. The Ga–N bond length is 1.98 Å. There are a spread of Ga–F bond distances ranging from 1.87–1.97 Å. N3- is bonded in a distorted trigonal non-coplanar geometry to one Ga3+ and three H1+ atoms. There is two shorter (1.03 Å) and one longer (1.04 Å) N–H bond length. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a linear geometry to two equivalent Ga3+ atoms. In the second F1- site, F1- is bonded in a linear geometry to two equivalent Ga3+ atoms. In the third F1- site, F1- is bonded in a single-bond geometry to one Ga3+ atom.
