X-ray diffraction study of two crystalline modifications of С{sub 2}Н{sub 5}O–C{sub 6}H{sub 3}(OН)–СН=N–C{sub 6}H{sub 4}–CH{sub 3} (1a, sp. gr. Р2{sub 1}/n, and 1b, sp. gr. С2/c) and С{sub 3}H{sub 7}O–C{sub 6}H{sub 3}(OН)–СН=N–C{sub 6}H{sub 4}–C{sub 4}H{sub 9} (2, sp. gr. Р2{sub 1}2{sub 1}2{sub 1}) 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.
