Materials Data on H3C3N5 by Materials Project
C3N5H3 is black P structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four C3N5H3 clusters. there are six inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms. There is two shorter (1.33 Å) and one longer (1.41 Å) C–N bond length. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms. There is two shorter (1.33 Å) and one longer (1.41 Å) C–N bond length. In the third C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms. There are a spread of C–N bond distances ranging from 1.34–1.36 Å. In the fourth C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms. There is two shorter (1.33 Å) and one longer (1.41 Å) C–N bond length. In the fifth C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms. There is one shorter (1.33 Å) and two longer (1.36 Å) C–N bond length. In the sixth C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms. There is one shorter (1.34 Å) and two longer (1.35 Å) C–N bond length. There are ten inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the second N3- site, N3- is bonded in a bent 120 degrees geometry to two C4+ atoms. In the third N3- site, N3- is bonded in a bent 120 degrees geometry to two C4+ atoms. In the fourth N3- site, N3- is bonded in a bent 120 degrees geometry to two C4+ atoms. In the fifth N3- site, N3- is bonded in a bent 120 degrees geometry to two C4+ atoms. In the sixth N3- site, N3- is bonded in a trigonal planar geometry to three C4+ atoms. In the seventh N3- site, N3- is bonded in a bent 120 degrees geometry to two C4+ atoms. In the eighth N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two equivalent H1+ atoms. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. In the ninth N3- site, N3- is bonded in a bent 120 degrees geometry to two C4+ atoms. In the tenth N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. There is one shorter (1.01 Å) and one longer (1.02 Å) N–H bond length. There are five 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. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom.
