TL;DR: It is shown that the presence of He atoms causes strong electron localization and makes this material insulating, and it is predicted that the existence of Na2HeO with a similar structure at pressures above 15 GPa is predicted.

TL;DR: The first observation of the formation of polyhydrides of Na (NaH3 and NaH7) above 40 GPa and 2,000 K is reported, supported by synchrotron X-ray diffraction and Raman spectroscopy in a laser-heated diamond anvil cell and theoretical random structure searching, which both agree on the stable structures and compositions.
