Preferred Label : adduct;
IUPAC definition : 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, π-adduct.;
