Materials Data on Cs2AlInH6 by Materials Project
Cs2AlH6In crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of four indium molecules and one Cs2AlH6 framework. In the Cs2AlH6 framework, Cs1+ is bonded to twelve equivalent H1- atoms to form distorted CsH12 cuboctahedra that share corners with twelve equivalent CsH12 cuboctahedra, faces with six equivalent CsH12 cuboctahedra, and faces with four equivalent AlH6 octahedra. All Cs–H bond lengths are 3.15 Å. Al3+ is bonded to six equivalent H1- atoms to form AlH6 octahedra that share faces with eight equivalent CsH12 cuboctahedra. All Al–H bond lengths are 1.80 Å. H1- is bonded in a single-bond geometry to four equivalent Cs1+ and one Al3+ atom.
