X-ray crystal and computational structural study of (E)-2-[(2-chloro-phenyl)-iminometh-yl]-4-methoxy-phenol
Abstract:
In the mol-ecule of the title compound, C(14)H(12)ClNO, the two aromatic rings are oriented at a dihedral angle of 12.28 (7)°. An intra-molecular O-H⋯N hydrogen bond results in the formation of a nearly planar six-membered ring, which is oriented with respect to the aromatic rings at dihedral angles of 0.18 (5) and 12.10 (6)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains along the c axis. There is a C-H⋯π contact between the methyl group and the chloro-phenyl ring and a π-π contact between the two benzene rings [centroid-centroid distance = 3.866 (1) Å].

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
