Cs10H[Ga3H8]3: A Hydrogenous Zintl phase Containing Propane-Like Polyanions [Ga3H8]3– and Interstitial Hydrogen

The hydrogenous Zintl-phase Cs10H[Ga3H8]3 containing propane-like polyanions [Ga3H(D)8]3– was successfully synthesized by direct hydrogenation of a 1:1 Cs/Ga metal mixture and characterized by powder X-ray and neutron diffraction. The charge of the polyanions is balanced by two different species of...

Description
Summary:The hydrogenous Zintl-phase Cs10H[Ga3H8]3 containing propane-like polyanions [Ga3H(D)8]3– was successfully synthesized by direct hydrogenation of a 1:1 Cs/Ga metal mixture and characterized by powder X-ray and neutron diffraction. The charge of the polyanions is balanced by two different species of cations, hydrogen-centered octahedra [H(D)Cs6]5+ and isolated Cs+. The structure crystallizes in the hexagonal space group P63/mcm (193) with the cell parameters a = 11.1108(3) Å, c = 18.2149(5) Å, Z = 2.
