Prediction of the existence of a stable new form of water: H4⁢O2+ or Aquodiium

Amazing stuff! Exotic!

We still do not even understand water! However, we are inundated on a daily basis with the Global Warming hoax and Climate Change religion!

The Russian-Chinese cooperation in science seems to work well despite the Russo-Ukrainian war.

"... Scientists have discovered the potential existence of a bizarre new molecule related to water. Dubbed “aquodiium,” this ion could form under extreme conditions and may explain some of the weirdness of our solar system’s ice giant planets. ..."

"Skoltech scientists and their Chinese colleagues have determined the conditions that enable the existence of a very peculiar ion. Dubbed aquodiium, it can be conceptualized as an ordinary neutral molecule of water with two additional protons stuck to it, resulting in a net double positive charge. The team suggests that the ion could be stable in the interior of the ice giants Uranus and Neptune, and if so, it must play a part in the mechanism that gives rise to these planets’ unusual magnetic fields.

From the abstract:

"Aquodiium (H4⁢O2+), an isoelectronic analog of the ammonium ion (NH+

4), can theoretically be formed by combining a molecule of water (H2⁢O) with two protons. However, stable aquodiium has never been reported because of the high energy cost during the second protonation after hydronium (H3⁢O+). Here, by performing ab initio evolutionary structure searches combined with first-principles calculations, stable ionic phases, H4⁢O⁢F2 and H4⁢O⁢F2·HF, were predicted to be thermodynamically stable at high pressure. Analysis of bond lengths and electron density supports the formation of aquodiium under pressure in these two phases. Moreover, ab initio molecular dynamics simulations reveal that these ionic phases will enter the superionic states at lower temperatures compared to water ice. For H4⁢O⁢F2·HF, there is a plastic phase region where aquodiium ions exhibit free rotation. All aquodiium ions are fully preserved below 1000 K in these ionic phases, while after entering the diffusion state, only the H4⁢O⁢F2 phase keeps H4⁢O2+ ions. Our results suggest that pressure stabilizes the H4⁢O2+ ion, presenting an important addition to traditional physical and chemical theories such as the valence shell electron pair repulsion model, proton transfer, and acid-base theory."
