| مستخلص: |
Cocrystals of 2,7‐dihydroxynaphthalene (DHN, or naphthalene‐2,7‐diol) with isoniazid (pyridine‐4‐carbohydrazide) (INH), denoted DHN–INH [C10H8O2·C6H7N3O, (I)], and piracetam [2‐(2‐oxopyrrolidin‐1‐yl)acetamide] (PIR), denoted DHN–PIR [C10H8O2·C6H10N2O2, (II)], were obtained by the solvent‐assisted grinding method and characterized by IR spectroscopy, powder X‐ray diffraction and single‐crystal X‐ray diffraction. Cocrystal (I) crystallized in the triclinic space group P and showed a 2:2 stoichiometry. DHN and INH molecules are connected by O—H...N(pyridine) and O—H...N(hydrazide) hydrogen bonds. Cocrystal (II) crystallized in the space group Pca21 with a 1:1 stoichiometry. DHN and PIR molecules are connected by O—H...O=C hydrogen bonds. The supramolecular architecture of cocrystal (I) showed interlinked supramolecular tapes; meanwhile, in cocrystal (II), interlinked supramolecular sheets were observed. [ABSTRACT FROM AUTHOR] |
