Materials Data on LiH12AuC4(SO3)4 by Materials Project
LiAuC4H12(SO3)4 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. Li1+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Li–O bond lengths are 2.00 Å. Au3+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. All Au–O bond lengths are 2.04 Å. C4+ is bonded in a trigonal non-coplanar geometry to three H1+ and one S2- atom. There is one shorter (1.09 Å) and two longer (1.10 Å) C–H bond length. The C–S bond length is 1.77 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C4+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C4+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C4+ atom. S2- is bonded in a distorted trigonal non-coplanar geometry to one C4+ and three O2- atoms. There are a spread of S–O bond distances ranging from 1.45–1.56 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Au3+ 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 bent 150 degrees geometry to one Li1+ and one S2- atom.
