Materials Data on BiH25C8(SO2)6 by Materials Project
(CH3)6C2BiH6S5O8HSO4 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of twelve methane molecules; one sulfate, hydrogen, compd. with sulfuric acid (1:1) molecule; and one C2BiH6S5O8 cluster. In the C2BiH6S5O8 cluster, there are two inequivalent C1+ sites. In the first C1+ site, C1+ 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 1.79 Å. In the second C1+ site, C1+ is bonded in a trigonal non-coplanar geometry to three H1+ and one S2- atom. All C–H bond lengths are 1.10 Å. The C–S bond length is 1.79 Å. Bi3+ is bonded in a 6-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.36–3.02 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. There are five inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted single-bond geometry to one O2- atom. The S–O bond length is 1.55 Å. In the second S2- site, S2- is bonded in a distorted trigonal non-coplanar geometry to two C1+ and one O2- atom. The S–O bond length is 1.53 Å. In the third S2- site, S2- is bonded in a distorted single-bond geometry to one O2- atom. The S–O bond length is 1.55 Å. In the fourth S2- site, S2- is bonded in a distorted single-bond geometry to one O2- atom. The S–O bond length is 1.55 Å. In the fifth S2- site, S2- is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.53 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Bi3+ and one S2- atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Bi3+ and one S2- atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Bi3+ and one S2- atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Bi3+ and one S2- atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Bi3+ and one S2- atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Bi3+ and one S2- atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Bi3+ and one S2- atom.
