High pressure compound containing bridging hydrogen cations might be found inside Neptune and Uranus
An unprecedented high pressure reaction between ammonia and hydrogen might create a chemical bond never seen before: a hydrogen cation bridging two nitrogen atoms. Nitrogen heptahydride – which is predicted to have the highest hydrogen storage capacity of any material – could even be found on Uranus and Neptune.
