A compound containing two amido groups united with one or
more basic or positive radicals, -- as contrasted with a

Note: In chemical nomenclature, if any amine or diamine is
named by prefixing the nitrogen group, the name of the
latter takes the form of amido, diamido, etc., thus
ethylene diamine, C2H4.(NH2)2, is also called
diamido-ethylene.
