description: FeC3N3H12O8C3H2(NO)3(H2O)2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four cyanuric acid molecules; eight water molecules; and two FeC3N3H12O8 ribbons oriented in the (0, 0, 1) direction. In each FeC3N3H12O8 ribbon, Fe2+ is bonded in an octahedral geometry to one N3- and five O2- atoms. The Fe–N bond length is 2.23 Å. There are a spread of Fe–O bond distances ranging from 2.12–2.23 Å. There are three inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to two N3- and one O2- atom. Both C–N bond lengths are 1.37 Å. The C–O bond length is 1.24 Å. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to two N3- and one O2- atom. There is one shorter (1.36 Å) and one longer (1.40 Å) C–N bond length. The C–O bond length is 1.25 Å. In the third C4+ site, C4+ is bonded in a trigonal planar geometry to two N3- and one O2- atom. There is one shorter (1.37 Å) and one longer (1.39 Å) C–N bond length. The C–O bond length is 1.25 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to two C4+ and one H1+ atom. The N–H bond length is 1.04 Å. In the second N3- site, N3- is bonded in a trigonal planar geometry to one Fe2+ and two C4+ atoms. In the third N3- site, N3- is bonded in a trigonal planar geometry to two C4+ and one H1+ atom. The N–H bond length is 1.04 Å. There are twelve inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (0.99 Å) and one longer (1.69 Å) H–O bond length. 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 single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth 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 fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the ninth 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 tenth 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 eleventh 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 twelfth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Fe2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Fe2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted water-like geometry to one Fe2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one C4+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one C4+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one C4+ atom. In the seventh O2- site, O2- is bonded in a distorted water-like geometry to one Fe2+ and two H1+ atoms. In the eighth O2- site, O2- is bonded in a distorted water-like geometry to one Fe2+ and two H1+ atoms.
