Structural studies in the solid state by X-raycrystallography and by 13C and 15N CPMAS NMRspectroscopy carried out on a series of 2-aminotroponimine derivatives 2−5 has allowed to establish the existence of hydrogen bonding and to determine the most stable tautomer. Almost all the structures reflect the classical double-well potential function for the N−H···N hydrogen bonds. Only in the case of the
