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.

(NH6O2)2SiF6 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight NH6O2 clusters and four SiF6 clusters. In each NH6O2 cluster, N1- is bonded in a tetrahedral geometry to three H1+ and one O2- atom. There is two shorter (1.04 Å) and one longer (1.05 Å) N–H bond length. The N–O bond length is 1.41 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom. In the fourth H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.59 Å) H–O bond length. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to three H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to one N1- and one H1+ atom. In each SiF6 cluster, Si4+ is bonded in an octahedral geometry to six F1- atoms. There is two shorter (1.71 Å) and four longer (1.73 Å) Si–F bond length. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Si4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Si4+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Si4+ atom.
