Crystal Structure of Schiff base Compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol
Single crystals of Schiff base compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol (1) were grown by the slow evaporation technique at room temperature. The crystal structure of the title compound was determined by single crystal X-ray diffraction. The title compound crystallizes in the monoclinic system, space group P21, with two symmetry independent molecules. Intramolecular O-H···N hydr...
متن کامل4-Chloro-2-[(4-chlorobenzylidene)amino]phenol
In the title Schiff base compound, C(13)H(9)Cl(2)NO, the mol-ecule displays an E conformation about the imine C=N double bond, with a dihedral angle of 8.09 (11)° between the two benzene rings. In the crystal, mol-ecules are linked by a single O-H⋯O hydrogen bond, giving one-dimensional chains which extend along (100).
متن کاملCrystal structure of 4-[(E)-(4-nitrobenzylidene)amino]phenol
The asymmetric unit of the title compound, C13H10N2O3, contains four independent mol-ecules (I, II, III and IV). Mol-ecule IV shows whole-mol-ecule disorder over two sets of adjacent sites in a 0.669 (10):0.331 (10) ratio. The dihedral angles between the aromatic rings are 32.30 (13)° in mol-ecule I, 2.24 (14)° in II, 41.61 (13)° in III, 5.0 (5)° in IV (major component) and 10.2 (3)° in IV (min...
متن کامل2-(4-Hydroxyphenylsulfonyl)phenol
The title compound, C(12)H(10)O(4)S, is a phenolic color developer used for leuco colorants. The two benzene rings with substituent hydr-oxy groups are nearly perpendicular to each other [dihedral angle = 91.5 (1)°]. There are inter-molecular O-H⋯O hydrogen bonds between an OH group of one mol-ecule and a sulfonyl O atom of a neighboring mol-ecule. One mol-ecule is hydrogen bonded to four symme...
متن کامل4-(2-Hydroxyethoxy)phenol
The asymmetric unit of the title compound, C8H10O3, contains four mol-ecules, which differ in the orientation of the hy--droxy-ethyl group [O-C-C-O torsion angles = -168.89 (17), 72.9 (2), -65.8 (2) and 71.8 (2)°], as well as the orientation of the hy-droxy H atoms. Furthermore, the crystal structure displays two different types of strong hydrogen bond. The first is between an alcohol O-H and a...
