    (Japan Society for Analytical Chemistry, 2008) Tanak, Hasan; Erşahin, Ferda; Aar, Erbil; Büyükgüngör, Orhan; Yavuz, Metin
    The crystal structure of the title compound, C14H12N2O4, was determined by a single-crystal X-ray diffraction technique, (Fig. 1). The title compound crystallizes in the orthorhombic space group Pca21 with the following unit-cell parameters: a = 18.4391(15)Å, b = 4.2710(2)Å, c = 32.2187(16)Å and V = 2537.3(3)Å3. The crystal data were solved with a final R = 0.062 using 2394 independent reflections. There are two molecules in the asymmetric unit. The title compound adopts the keto-amine tautomeric form. In the structure, there are N-H...O and C-H ···O intramolecular hydrogen bonds and C-H · · ·O intermolecular hydrogen bonds. 2008 © The Japan Society for Analytical Chemistry.

    (E)-4-Bromo-2-(2-methoxyphenyliminomethyl) phenol
    (Acta Crystallographica Section E Structure Reports Online, 2007) Gül, Zarife Sibel; Erşahin, Ferda; Ağar, Erbil; Işık, Şamil
    The molecule of the title compound, C14H12BrNO2, is almost planar and the dihedral angle between the planes of the two aromatic rings is 3.8 (2) . The molecule exists in the crystal structure in the phenol–imine tautomeric form, with the H atom located on O rather than on N. This H atom is involved in a strong intramolecular hydrogen bond.
