Classified as: Type 10 Lewis Acid/Base Complexation Chemistry

Onium Ion Lewis acids form classic charge controlled (highly ionic) complexes with Complex anion Lewis bases. An example of such a complex is ammonium tetrafluoroborate.

Type 10 complexes are soluble in polar solvents in which the ions are fully dissociated.

For more information look in the Chemogenesis webbook sections on Lewis acids and Lewis bases and the Lewis acid/base interaction matrix.
