Abstract
The X-ray structures of the two compounds carpaine (C28H50N2O4) and carpain e dihydrobromide monohydrate (C28H52N2O42+. 2Br(-). H2O) have been determin ed, together with the absolute configuration of the hydrobromide derivative , The structure of the hydrobromide derivative shows that the molecule is f lexible and the changes in the conformations are brought about by the hydro gen bonding of the protonated-N atoms with the two Br atoms and the water m olecule.
