Materials Data on NdH12S2NO12 by Materials Project
NdH6S2O11NH4H2O crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four ammonium molecules; four water molecules; and two NdH6S2O11 sheets oriented in the (0, 1, 0) direction. In each NdH6S2O11 sheet, Nd3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Nd–O bond distances ranging from 2.43–2.59 Å. There are six 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 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 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 O2- atom. The H–O bond length is 0.99 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. There are two inequivalent S2+ sites. In the first S2+ site, S2+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.48–1.51 Å. In the second S2+ site, S2+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.48 Å) and two longer (1.50 Å) S–O bond length. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Nd3+ and one S2+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Nd3+ and one S2+ atom. In the fourth O2- site, O2- is bonded in a water-like geometry to one Nd3+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Nd3+ and one S2+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Nd3+ and one S2+ atom. In the seventh O2- site, O2- is bonded in a water-like geometry to one Nd3+ and two H1+ atoms. In the eighth O2- site, O2- is bonded in a distorted water-like geometry to one Nd3+ and two H1+ atoms. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Nd3+ and one S2+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one Nd3+ and one S2+ atom. In the eleventh O2- site, O2- is bonded in a single-bond geometry to one S2+ atom.
