description: ZnC3N7H12O6NH2H2O crystallizes in the monoclinic Cc space group. The structure is zero-dimensional and consists of four ammonia molecules, four water molecules, and four ZnC3N7H12O6 clusters. In each ZnC3N7H12O6 cluster, Zn2+ is bonded in an octahedral geometry to three N2- and three O2- atoms. There are a spread of Zn–N bond distances ranging from 2.18–2.25 Å. There are a spread of Zn–O bond distances ranging from 2.10–2.13 Å. There are three inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to one N2- and two O2- atoms. The C–N bond length is 1.36 Å. There is one shorter (1.28 Å) and one longer (1.29 Å) C–O bond length. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to one N2- and two O2- atoms. The C–N bond length is 1.38 Å. There is one shorter (1.28 Å) and one longer (1.29 Å) C–O bond length. In the third C4+ site, C4+ is bonded in a trigonal planar geometry to one N2- and two O2- atoms. The C–N bond length is 1.40 Å. There is one shorter (1.26 Å) and one longer (1.29 Å) C–O bond length. There are seven inequivalent N2- sites. In the first N2- site, N2- is bonded in a distorted water-like geometry to one Zn2+ and two H1+ atoms. Both N–H bond lengths are 1.03 Å. In the second N2- site, N2- is bonded in a distorted bent 120 degrees geometry to one C4+ and one H1+ atom. The N–H bond length is 1.05 Å. In the third N2- site, N2- is bonded in a distorted water-like geometry to one Zn2+, one N2-, and two H1+ atoms. The N–N bond length is 1.42 Å. There is one shorter (1.03 Å) and one longer (1.04 Å) N–H bond length. In the fourth N2- site, N2- is bonded in a 2-coordinate geometry to one C4+, one N2-, and one H1+ atom. The N–H bond length is 1.03 Å. In the fifth N2- site, N2- is bonded in a distorted water-like geometry to one Zn2+ and two H1+ atoms. There is one shorter (1.03 Å) and one longer (1.04 Å) N–H bond length. In the sixth N2- site, N2- is bonded in a 2-coordinate geometry to one C4+ and one H1+ atom. The N–H bond length is 1.02 Å. In the seventh N2- site, N2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There are a spread of N–H bond distances ranging from 1.04–1.07 Å. There are twelve inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the eleventh H1+ site, H1+ is bonded in a distorted single-bond geometry to one N2- and one O2- atom. The H–O bond length is 1.63 Å. In the twelfth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. There are six inequivalent O2- sites.
