Materials Data on SiH8C2NClO by Materials Project
SiC2NH8OCl crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two SiC2NH8OCl clusters. Si4+ is bonded in a 5-coordinate geometry to one N3-, two H1+, one O2-, and one Cl1- atom. The Si–N bond length is 2.06 Å. Both Si–H bond lengths are 1.48 Å. The Si–O bond length is 1.69 Å. The Si–Cl bond length is 2.13 Å. There are two inequivalent C3- sites. In the first C3- site, C3- is bonded to one N3- and three H1+ atoms to form corner-sharing CH3N tetrahedra. The C–N bond length is 1.46 Å. All C–H bond lengths are 1.10 Å. In the second C3- site, C3- is bonded to one N3- and three H1+ atoms to form corner-sharing CH3N tetrahedra. The C–N bond length is 1.46 Å. All C–H bond lengths are 1.10 Å. N3- is bonded in a distorted trigonal non-coplanar geometry to one Si4+, two C3-, and one O2- atom. The N–O bond length is 1.50 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one Si4+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one Si4+ atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C3- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C3- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one C3- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one C3- atom. O2- is bonded in an L-shaped geometry to one Si4+ and one N3- atom. Cl1- is bonded in a single-bond geometry to one Si4+ atom.
