description: Al2H10S3O17 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with four SO4 tetrahedra. There is two shorter (1.88 Å) and four longer (1.91 Å) Al–O bond length. In the second Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with four SO4 tetrahedra. There is four shorter (1.88 Å) and two longer (1.91 Å) Al–O bond length. In the third Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with three SO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.88–1.92 Å. There are ten inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.64 Å) H–O bond length. 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 tenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are three inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two AlO6 octahedra. The corner-sharing octahedra tilt angles range from 33–38°. There is two shorter (1.48 Å) and two longer (1.50 Å) S–O bond length. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two AlO6 octahedra. The corner-sharing octahedra tilt angles range from 35–37°. There are a spread of S–O bond distances ranging from 1.47–1.50 Å. In the third S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three AlO6 octahedra. The corner-sharing octahedra tilt angles range from 35–41°. There are a spread of S–O bond distances ranging from 1.47–1.49 Å. There are seventeen inequivalent O2- sites.
