Materials Data on La2H22S6N6O23 by Materials Project
(LaN3H10S3O11)2H2O crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of four water molecules and two LaN3H10S3O11 sheets oriented in the (1, 0, 0) direction. In each LaN3H10S3O11 sheet, La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.49–2.64 Å. There are three inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a distorted trigonal non-coplanar geometry to two H1+ and one S2- atom. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. The N–S bond length is 1.65 Å. In the second N5+ site, N5+ is bonded in a distorted trigonal non-coplanar geometry to two H1+ and one S2- atom. Both N–H bond lengths are 1.03 Å.

The N–S bond length is 1.68 Å. There are ten inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N5+ atom. 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 N5+ atom. 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 N5+ atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N5+ atom. 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. 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 N5+ atom. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a tetrahedral geometry to one N5+ and three O2- atoms. All S–O bond lengths are 1.47 Å. In the second S2- site, S2- is bonded in a tetrahedral geometry to one N5+ and three O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.48 Å. In the third S2- site, S2- is bonded in a tetrahedral geometry to one N5+ and three O2- atoms. All S–O bond lengths are 1.47 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one La3+ and one S2- atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one La3+ and one S2- atom. In the third O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one La3+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one La3+ and one S2- atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one La3+ and one S2- atom.
