title: Materials Data on FeH10S2NO11 by Materials Project

description: FeNH8S2O11H2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four hydrogen molecules and one FeNH8S2O11 sheet oriented in the (0, 0, 1) direction. In the FeNH8S2O11 sheet, Fe3+ is bonded to five O2- atoms to form FeO5 trigonal bipyramids that share corners with four SO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 1.94–2.00 Å. N5+ is bonded in a tetrahedral geometry to three H1+ and one O2- atom. There are a spread of N–H bond distances ranging from 1.03–1.06 Å. The N–O bond length is 1.41 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a bent 150 degrees geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.57 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N5+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N5+ and one O2- atom. The H–O bond length is 1.69 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N5+ atom. In the fifth 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 sixth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.57 Å) H–O bond length. In the seventh 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 eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are two inequivalent S2+ sites. In the first S2+ site, S2+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent FeO5 trigonal bipyramids. There is two shorter (1.48 Å) and two longer (1.51 Å) S–O bond length. In the second S2+ site, S2+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent FeO5 trigonal bipyramids. There are a spread of S–O bond distances ranging from 1.45–1.53 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one S2+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S2+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Fe3+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Fe3+ and one S2+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Fe3+ and one S2+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Fe3+ and one S2+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to one H1+ and one S2+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Fe3+ and two H1+ atoms. In the tenth O2- site, O2- is bonded in a water-like geometry to one N5+ and one H1+ atom. In the eleventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three H1+ atoms.
