Abstract: Arising from a hydrogen bond between the OH group of one molecule and the quinuclidine N atom of an adjacent molecule, molecules of the title compound, C₁₉H₂₄N₂O, [also known as (3R,8S,9R)-10,11-dihydrocinchonidine] are linked [ON = 2.749 (4) Å] into a helical chain that runs along the shortest axis of the orthorhombic unit cell. The compound is isostructural with cinchonidine (which has a vinyl group instead of the ethyl group), whose structure has been described in detail [Oleksyn (1982). Acta Cryst. B38, 1832-1834].
