Materials Data on CrH10SO9 by Materials Project

CrH10SO9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Cr2+ sites. In the first Cr2+ site, Cr2+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with two equivalent SO4 tetrahedra. There are a spread of Cr–O bond distances ranging from 2.07–2.46 Å. In the second Cr2+ site, Cr2+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with two equivalent SO4 tetrahedra. There are a spread of Cr–O bond distances ranging from 2.05–2.58 Å. There are ten 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 0.99 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 distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.68 Å) H–O bond length. In the sixth 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 seventh H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.68 Å) H–O bond length. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (0.99 Å) and one longer (1.72 Å) H–O bond length. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.75 Å) H–O bond length. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two CrO6 octahedra. The corner-sharing octahedra tilt angles range from 46–48°. There is three shorter (1.49 Å) and one longer (1.51 Å) S–O bond length. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Cr2+, one H1+, and one S6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Cr2+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two H1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one H1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Cr2+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Cr2+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a distorted water-like geometry to one Cr2+ and two H1+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cr2+ and two H1+ atoms. In the ninth O2- site, O2- is bonded in a water-like geometry to two H1+ atoms.
