[EN] The X-ray crystal structure of a racemic triarylcarbinol derivate ((±)-1)
was determined. Compound (±)-1 crystallizes as a chiral structure in the noncentrosymmetric
Sohncke space group P21 and the crystals show a special case of
enantiomeric disorder with two molecules of opposite handedness sharing many of the
atomic positions in the asymmetric unit. The corresponding (R)- and (S)-enantiomers
of 1 were separated by chiral HPLC, and crystallized independently yielding single
crystals of both of them. The X-ray diffraction analysis of the crystals allowed the
determination of the absolute configuration of both enantiomers (R)-1 and (S)-1. Both
enantiomers establish intermolecular hydrogen bonds in the solid state, which induce
significant differences in their molecular arrangement when compared to racemic crystal
(±)-1.
