An intramolecular O-H...N hydrogen bond results in the formation of a nearly planar [maximum deviation 0.034 (13) Å] six-membered ring, which is oriented at dihedral angles of 0.91 (1) and 28.91 (12)° with respect to the aromatic rings. The title molecule is a phenol-imine tautomer, as evidenced by C-O, C-N and C-C bond lengths. In the crystal, molecules are linked by intermolecular C-H...O hydrogen bonds that generate C(8) chains.Öğe (E)-2-Ethoxy-6-[(4-ethoxyphenyl)iminomethyl]phenol(Acta Crystallographica Section E, 2010) Özek, Arzu; Koşar, Başak; Albayrak, Çiğdem; Büyükgüngör, Orhan[Abstract Not Available]Öğe (E)-4-Methoxy-2-(o-tolyliminomethyl)phenol(Acta Crystallographica Section E, 2009) Özek, Arzu; Büyükgüngör, Orhan; Albayrak, Çiğdem; Odabaşoğlu, MustafaIn the molecule of the title compound, C15H15NO2, the aromatic rings are oriented at a dihedral angle of 15.46 (6)°. An intramolecular O-H...N hydrogen bond results in the formation of a nearly planar six-membered ring [maximum deviation of 0.035 (5) Å for the N atom] which is almost coplanar with the adjacent ring, making a dihedral angle of 0.8 (3)°. The title organic molecule is a phenol-imine tautomer, as evidenced by the C-O, C-N and C-C bond lengths. Molecules are linked by intermolecular C-H...O hydrogen bonds that generate a C(5) chain. C-H...[pi] and [pi]-[pi] interactions exist in the structure. The [pi]-[pi] interaction occurs between the phenol ring and its symmetry equivalent at (1 - x, 1 - y, -z), with a centroid-centroid distance of 3.727 (7) Å and a plane-to-plane separation of 3.383 (5) Å, resulting in an offset angle of 24.82 (1)°.Öğe (E)-4-Methoxy-2-(p-tolyliminomethyl)phenol(Acta Crystallographica Section E, 2010) Koşar, Başak; Özek, Arzu; Albayrak, Çiğdem; Büyükgüngör, Orhan[Abstract Not Available]Öğe X-ray and computational structural study of (E)-2-(4-chlorophenyliminomethyl)-4-methoxyphenol(Acta Crystallographica Section E, 2008) Özek, Arzu; Büyükgüngör, Orhan; Albayrak, Çiğdem; Odabaşoğlu, MustafaIn the molecule of the title compound, C14H12ClNO2, the two aromatic rings are oriented at a dihedral angle of 5.92 (7)°. An intramolecular O-H...N hydrogen bond results in the formation of a nearly planar six-membered ring, which is oriented at dihedral angles of 1.55 (4) and 5.95 (4)° with respect to the phenol and chlorophenyl rings, respectively.
