Abstract

LaH4SO6NH2O2(H2O)2H2SO2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four hydroxylamine, n-hydroxy- molecules; eight water molecules; four H2SO2 clusters; and four LaH4SO6 ribbons oriented in the (1, 0, 0) direction. In each H2SO2 cluster, there are two 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 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one S2+ atom. The H–S bond length is 1.38 Å. S2+ is bonded in a distorted trigonal non-coplanar geometry to one H1+ and two O2- atoms. There is one shorter (1.50 Å) and one longer (1.68 Å) S–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one S2+ atom. In each LaH4SO6 ribbon, La3+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of La–O bond distances ranging from 2.06–2.71 Å. There are four 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 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. S2+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of S–O bond distances ranging from 1.50–1.74 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one La3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one La3+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one La3+ and 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 single-bond geometry to one H1+ and one S2+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one La3+ and one S2+ atom.
