Abstract
X-ray diffraction study of two crystalline modifications of С2Н5O–C6H3(OН)–СН=N–C6H4–CH3 (1a, sp. gr. Р21/n, and 1b, sp. gr. С2/c) and С3H7O–C6H3(OН)–СН=N–C6H4–C4H9 (2, sp. gr. Р212121) has been performed. The 1a crystal structure contains two independent molecules. The molecules are conformationally nonrigid with respect to the mutual rotation of benzene rings; the dihedral angles between their planes are 29.19° and 26.00° in the independent molecules of 1a, 18.72° in the molecule of 1b, and 50.35° in the molecule of 2. The crystal packing of the compounds is discussed.
