A hydronium ion is formed when a positively charged hydrogen ion bonds with a molecule of water through a coordinate covalent bond.
Eigen placed the hydronium ion at the centre of an H9O4+ complex in which the hydronium is strongly hydrogen-bonded to 3 neighbouring water molecules (3). Eigen proposed an H5O2+ complex, in which the proton is shared equally by two water molecules (4).
