posted on 2013-06-17, 00:00 authored by Henrik Fahlquist, Dag NoréusThe 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.
