- Аннотация: Three polymorphs of first synthesized (RS,SR)-3-(α,4-dichlorobenzyl)-3-hydroxyindolin-2-one are characterized by single crystal X-ray diffraction. Since the configuration of the 3-(α,4-dichloroоbenzyl)-3-hydroxyindolin-2-one fragment is identical in all three molecules, in one case, polymorphism is related to a conformational change due to a noticeable turn of the aromatic substituent of the molecule; in the second case, due to a change in the system of intermolecular interactions. The Hirshfeld surface analysis reveals distinctions in weak non-covalent interactions in the crystals of polymorphs. Despite that the hydrogen bonded motif is somewhat weaker in the 1b polymorph crystal, it is characterized by a closer crystal packing as compared to polymorphs 1a and 1c whose crystals have another type of the conformer.
