title: Materials Data on Li3AsH16(SO2)4 by Materials Project

description: Li3(H2O)8AsS4 crystallizes in the monoclinic P2/c space group. The structure is one-dimensional and consists of four AsS4 clusters and one Li3(H2O)8 ribbon oriented in the (0, 0, 1) direction. In each AsS4 cluster, As5+ is bonded in a tetrahedral geometry to four S2- atoms. There are two shorter (2.18 Å) and two longer (2.21 Å) As–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a single-bond geometry to one As5+ atom. In the second S2- site, S2- is bonded in a single-bond geometry to one As5+ atom. In the Li3(H2O)8 ribbon, there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with two equivalent LiO4 tetrahedra and edges with two equivalent LiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.15–2.26 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share a cornercorner with one LiO4 tetrahedra and an edgeedge with one LiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.07–2.31 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form corner-sharing LiO4 tetrahedra. The corner-sharing octahedral tilt angles are 56°. There are two shorter (2.01 Å) and two longer (2.02 Å) Li–O bond lengths. In the fourth Li1+ site, Li1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.91–2.03 Å. There are sixteen 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 1.00 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth 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 fifth 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 sixth 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 seventh 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 eighth 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 ninth 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 tenth 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 eleventh 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 twelfth 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 thirteenth 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 fourteenth 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 fifteenth 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 sixteenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to two Li1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to two Li1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted water-like geometry to two Li1+ and two H1+ atoms.

In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Li1+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a distorted water-like geometry to two Li1+ and two H1+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+ and two H1+ atoms.
