A new chemical species
AB, each molecular entity
of which is formed by direct combination of two separate molecular entities A and
B in such a way that there is change in connectivity
, but no loss, of atoms within the moieties
A and B. Stoichiometries other than 1:1 are also possible, e.g. a bis-adduct (2:1).
An intramolecular adduct
can be formed when A and B are groups contained within the same molecular entity.
This is a general term which, whenever appropriate, should be used in preference to
the less explicit term complex
. It is also used specifically for products of an addition reaction
. For examples, see Lewis adduct
, Meisenheimer adduct
