Materials Data on LaH6S3(NO3)3 by Materials Project

Abstract

La(NH2SO3)3 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are six shorter (2.47 Å) and three longer (2.75 Å) La–O bond lengths. 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 1.66 Å. There are two 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 N5+ atom. 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 1.45–1.48 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one La3+ and one S2- atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one La3+ and one S2- atom. In the third O2- site, O2- is bonded in a single-bond geometry to one La3+ and one S2- atom.
