Dimorphism of ethyl 1,4-dihydro-2,4,6-triphenylpyridine-3-carboxylate.
The title compound, C26H23NO2, (Ia) and (Ib), shows polymorphism with crystals obtained from different solvents displaying different crystal structures. However, it is not the geometry of the single molecules nor the hydrogen-bond pattern that is different in (Ia) and (Ib), but the way in which the hydrogen-bonded chains, running along the a-axis direction, are arranged with respect to each other.
