Usage Examples English
  • In condensed matter physics and inorganic chemistry the cation-anion radius ratio (also: radius ratio rule) is the ratio of the ionic radius of the cation to the ionic radius of the anion in a cation-anion compound.
  • Three other possible structures, two classical structures (the homoallyl cation and cyclobutyl cation) and a more highly delocalized non-classical structure (the tricyclobutonium ion), are now known to be less stable isomers (or merely a transition state rather than an energy minimum in the case of the cyclobutyl cation).
  • The α-terpinyl cation (5) then undergoes a 1,2 hydride shift via a Wagner–Meerwein rearrangement, leading to the formation of the terpinen-4-yl cation (6).
  • Other possibilities for the electrophile include (chloromethyl)oxonium cation (ClH2C–OH2+) or chlorocarbenium cation (ClCH2+), which may be formed in the presence of zinc chloride.
  • The most studied cation–π interactions involve binding between an aromatic π system and an alkali metal or nitrogenous cation.

  • For compounds that contain cation-cation or anion-anion bonds it is usually possible to transform these homoionic bonds into cation-anion bonds either by treating the atoms linked by the homoionic bond as a single complex cation (e.g., Hg22+), or by treating the bonding electrons in the homoionic bond as a pseudo-anion to transform a cation-cation bond into two cation - pseudo-anion bonds, e.g., Hg2+-e2−-Hg2+.
  • hexyl cation is analogous to the previously well-studied aromatic cyclopropenyl cation.
  • LPP then forms a resonance-stabilized cation by loss of the pyrophosphate group.
  • Analogous selenates also occur. The possible combinations of univalent cation, trivalent cation, and anion depends on the sizes of the ions.
  • Cation occlusion is now considered an essential property of all ATP-driven cation pumps and also other coupled cation transport systems (e.g. cation exchangers or co-transport proteins).

  • The trihydrogen cation or protonated molecular hydrogen is a cation (positive ion) with formula [...] , consisting of three hydrogen nuclei (protons) sharing two electrons.
  • The cyclopropenium ion is the cation with the formula [...].
  • The terms "hydrazinium" and "hydrazine" may also be used for the doubly protonated cation [...] , more properly called hydrazinediium or hydrazinium(2+).
  • The oxalyl cation, also known as "oxalic", has the chemical formula [...]2+. It is the cation derived from oxalic acid.
  • The osmocenium cation [...]+ dimerizes, forming a binuclear complex with an Os-Os bond. In contrast, the decamethylosmocenium cation [...]+ is stable as the monomer.
