Materials Data on Ca2AlH8S2Cl(O6F)2 by Materials Project
Abstract
Ca2AlH8S2Cl(O6F)2 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. Ca2+ is bonded to four equivalent O2-, one Cl1-, and one F1- atom to form CaClO4F octahedra that share a cornercorner with one CaClO4F octahedra, a cornercorner with one AlO4F2 octahedra, and corners with four equivalent SO4 tetrahedra. The corner-sharing octahedral tilt angles are 0°. All Ca–O bond lengths are 2.40 Å. The Ca–Cl bond length is 2.61 Å. The Ca–F bond length is 2.22 Å. Al3+ is bonded to four equivalent O2- and two equivalent F1- atoms to form AlO4F2 octahedra that share corners with two equivalent CaClO4F octahedra. The corner-sharing octahedral tilt angles are 0°. All Al–O bond lengths are 1.94 Å. Both Al–F bond lengths are 1.77 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. S6+ is bonded to four equivalent O2- atoms to form SO4 tetrahedra that share corners with four equivalent CaClO4F octahedra. The corner-sharing octahedral tilt angles are 50°. All S–O bond lengths are 1.49 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and twomore »
