abstract = {We report a new hydrogen clathrate hydrate synthesized at
1.2 GPa and 298 K documented by single-crystal x-ray
diffraction, Raman spectroscopy, and first-principles
calculations. The oxygen sublattice ofthe new clathrate
hydrate matches that of ice II, while hydrogen molecules are
in the ring cavities, whichresults in the trigonal $R3c$ or
$R \bar{3}c$ space group (proton ordered or disordered,
respectively) and thecomposition of $ðH_2 OÞ_6 H_2$. Raman
spectroscopy and theoretical calculations reveal a hydrogen
disorderednature of the new phase C0$_1$, distinct from the
well-known orderedC1clathrate, to which this new
structuretransforms upon compression and/or cooling. This
new clathrate phase can be viewed as a realization of
adisordered ice II, unobserved before, in contrast to all
other ordered ice structures.},
