Zundel cation. Two other well-known structures are the Zundel cation and the Eigen cation. The Eigen solvation structure has the hydronium ion at the center of an H 9 O + 4 complex in which the hydronium is strongly hydrogen-bonded to three neighbouring water molecules.

Proton transport mechanism and proton-hopping mechanism. The Grotthuss mechanism is now a general name for the proton-hopping mechanism. In liquid water the solvation of the excess proton is idealized by two forms: the H 9 O 4+ ( Eigen cation) or H 5 O 2+ ( Zundel cation ).
Zundel cation: H 5 O 2+ (named for Georg Zundel) Eigen cation: H 9 O 4+ (or H 3 O + •3H 2 O) (named for Manfred Eigen) Zundel cations and Eigen cations play an important role in proton diffusion according to the Grotthuss mechanism . In connection with acids, "hydrogen ions" typically refers to hydrons.
Georg Zundel (* 17. Mai 1931 in Tübingen; † 11. März 2007 in Salzburg) war deutscher Physiker, Unternehmer und friedenspolitisch engagierter Philanthrop .

The simplest hydrated form of the hydrogen cation, the hydronium (hydroxonium) ion H 3 O + (aq), is a key object of Arrhenius' definition of acid. Other "simple" hydrated forms include the Zundel cation H 5 O 2 + which is formed from a hydron and two water molecules, and the Eigen cation H 9 O 4 + , formed from a hydronium ion and three water ...
14. Juli 2022 · Many different forms of hydrated protons in water have been reported, among which the Zundel cation (H 5 O 2 +) and the Eigen cation (H 9 O 4 +) are the most representative ones. However, the configuration of Zundel and Eigen cations in bulk and interfacial water has been experimentally elusive. Vibrational spectroscopy, which is ...
19. Feb. 2016 · This moiety is nowadays known as the Zundel (Z) cation after Georg Zundel, who suggested that it gives rise to a 'continuum' in the infrared (IR) absorption of aqueous acidic solutions 5.
