Trihydrogen oxide is a predicted inorganic compound of hydrogen and oxygen with the chemical formula H3O.[1][2] This is still a hypothetical compound, one of the unstable hydrogen polyoxides. It is forecasted that the compound could constitute a thin layer of metallic liquid around the cores of Uranus and Neptune, being the source of their magnetic fields.[3] Calculations indicate the stability of H3O in solid, superionic, and fluid metallic states at the deep interior conditions of these planets.
