Materials Data on Tl2CuH12(SO7)2 by Materials Project

CuTl2H12(SO7)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Cu2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.97–2.48 Å. Tl1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Tl–O bond distances ranging from 2.84–3.32 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the second 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 (1.67 Å) H–O bond length. 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 single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.74 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. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.49–1.51 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Cu2+, one Tl1+, and two H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to one Cu2+, one Tl1+, and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Cu2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Tl1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Tl1+, two H1+, and one S6+ atom.

CuTlHSO5 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with four equivalent SO4 tetrahedra and edges with two equivalent CuO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.93–2.52 Å. Tl1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Tl–O bond distances ranging from 2.59–3.23 Å. 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 four equivalent CuO6 octahedra. The corner-sharing octahedra tilt angles range from 51–61°. There are a spread of S–O bond distances ranging from 1.47–1.56 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cu2+, one Tl1+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Cu2+, one Tl1+, and one S6+ atom.
