Type 10 Lewis Acid/Base Complexation Chemistry

Ionic Salts
Bonding: Onium ion/complex anion complexes are charge-controlled ionic salts. In polar solvents these species dissociate to give independently solvated ions which show minimal ion-pairing.
Charge: The charge on a Type 10 complex (salt) is always neutral.
Chemistry: Trimethyl and triethyl oxonium ions are powerful alkylating agents (ie they act as methyl cation and ethyl cation donor complexes) which require non-nucleophilic complex anion counter ions such as [BF4], [SbF6] or [PF6].
Congeneric Series:
