Cs2AlH6Ga crystallizes in the cubic Fm-3m space group. The structure consists of four 7440-55-3 atoms inside a Cs2AlH6 framework. In the Cs2AlH6 framework, Cs(1) is bonded to twelve equivalent H(1) atoms to form distorted CsH12 cuboctahedra that share corners with twelve equivalent Cs(1)H12 cuboctahedra, faces with six equivalent Cs(1)H12 cuboctahedra, and faces with four equivalent Al(1)H6 octahedra. Al(1) is bonded to six equivalent H(1) atoms to form AlH6 octahedra that share faces with eight equivalent Cs(1)H12 cuboctahedra. H(1) is bonded in a single-bond geometry to four equivalent Cs(1) and one Al(1) atom.
