Materials Data on H3OF by Materials Project

H3OF crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two H3OF sheets oriented in the (0, 0, 1) direction. there are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.04 Å. The H–F bond length is 1.43 Å. In the second H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.04 Å. The H–F bond length is 1.44 Å. O2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. F1- is bonded in a trigonal planar geometry to three H1+ atoms.

Materials Data on SiH12N2(O2F3)2 by Materials Project

H2SiF2(NH2OF)2(H3OF)2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four difluorosilane molecules, four hydrogen molecules, eight water-hydrogen fluoride molecules, and eight NH2OF clusters. In each NH2OF cluster, N1- is bonded in a trigonal planar geometry to two H1+ and one O2- atom. There is one shorter (1.06 Å) and one longer (1.52 Å) N–H bond length. The N–O bond length is 1.21 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to one N1- and one F1- atom. The H–F bond length is 1.03 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom. O2- is bonded in a single-bond geometry to one N1- atom. F1- is bonded in a single-bond geometry to one H1+ atom.
