description: Si2C7N2H18 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four schembl12447972 molecules. there are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded in a tetrahedral geometry to three C+2.86- and one N3- atom. All Si–C bond lengths are 1.88 Å. The Si–N bond length is 1.73 Å. In the second Si4+ site, Si4+ is bonded in a tetrahedral geometry to three C+2.86- and one N3- atom. There is one shorter (1.87 Å) and two longer (1.88 Å) Si–C bond length. The Si–N bond length is 1.73 Å. There are seven inequivalent C+2.86- sites. In the first C+2.86- site, C+2.86- is bonded to one Si4+ and three H1+ atoms to form corner-sharing CSiH3 tetrahedra. All C–H bond lengths are 1.10 Å. In the second C+2.86- site, C+2.86- is bonded to one Si4+ and three H1+ atoms to form corner-sharing CSiH3 tetrahedra. All C–H bond lengths are 1.10 Å.

In the fifth C+2.86- site, C+2.86- is bonded in a linear geometry to two N3- atoms. There is one shorter (1.21 Å) and one longer (1.22 Å) C–N bond length. In the sixth C+2.86- site, C+2.86- is bonded to one Si4+ and three H1+ atoms to form corner-sharing CSiH3 tetrahedra. All C–H bond lengths are 1.10 Å. In the seventh C+2.86- site, C+2.86- is bonded to one Si4+ and three H1+ atoms to form corner-sharing CSiH3 tetrahedra. All C–H bond lengths are 1.10 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a linear geometry to one Si4+ and one C+2.86- atom. In the second N3- site, N3- is bonded in a bent 150 degrees geometry to one Si4+ and one C+2.86- atom.
