An ion formed by direct combination of two separate molecular entities, usually an ion and a neutral molecule, in such a way that there is change in connectivity promoted by intermolecular binding, but no loss of atoms within the precursor entities. Normally a stoichiometry of 1:1 is observed, but other stoichiometries are also possible, e.g. a bis-adduct (2:1). An intramolecular adduct can also be formed for binding of different groups contained within the same molecular entity. Adduct ion is a general term which, whenever appropriate, should be used in preference to the less explicit term complex ion. It is also used specifically for products of an (cyclo)addition ion/molecule reaction. For examples, the Diels-Alder adduct ion. | |||
