title: Materials Data on ZnH7C4N3O7 by Materials Project

description: ZnC4N3H7O7 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one ZnC4N3H7O7 sheet oriented in the (1, 0, 0) direction. Zn2+ is bonded in an octahedral geometry to one N3- and five O2- atoms. The Zn–N bond length is 2.18 Å. There are a spread of Zn–O bond distances ranging from 2.09–2.16 Å. There are four inequivalent C+3.50+ sites. In the first C+3.50+ site, C+3.50+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.29 Å) C–O bond length. In the second C+3.50+ site, C+3.50+ is bonded in a bent 120 degrees geometry to two N3- atoms. There is one shorter (1.34 Å) and one longer (1.36 Å) C–N bond length. In the third C+3.50+ site, C+3.50+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.28 Å) C–O bond length. In the fourth C+3.50+ site, C+3.50+ is bonded in a water-like geometry to two N3- atoms. There is one shorter (1.34 Å) and one longer (1.35 Å) C–N bond length. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted water-like geometry to one C+3.50+ and one N3- atom. The N–N bond length is 1.34 Å. In the second N3- site, N3- is bonded in a 3-coordinate geometry to one Zn2+ and two C+3.50+ atoms. In the third N3- site, N3- is bonded in a 2-coordinate geometry to one C+3.50+, one N3-, and one H1+ atom. The N–H bond length is 1.05 Å. There are seven inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.65 Å) H–O bond length. In the fourth 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 fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the sixth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.65 Å) H–O bond length. In the seventh H1+ site, H1+ is bonded in a distorted linear geometry to one N3- and one O2- atom. The H–O bond length is 1.65 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one C+3.50+ and one H1+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Zn2+, one C+3.50+, and one H1+ atom. In the third O2- site, O2- is bonded in a distorted water-like geometry to one Zn2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Zn2+ and one C+3.50+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Zn2+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to one Zn2+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one C+3.50+ and one H1+ atom.
