Abstract:
In the title compound, C31H26Cl2N2O, the 4,6-di-chloro-phenol and the imidazole rings are almost coplanar, with a dihedral angle of 8.89 (6)° between them and an intra-molecular O-H⋯N hydrogen bond occurs between the rings. The dihedral angles subtended by the tert-butyl-phenyl ring and the two phenyl rings with the imidazole ring are 85.18 (9), 81.22 (9) and 19.00 (8)°, respectively. The methyl groups of the tert-butyl grouping are disordered over two sets of sites in 0.589 (5):0.411 (5) ratio. In the crystal, inversion dimers linked by pairs of weak C-H⋯Cl inter-actions generate R 2 2(24) loops.

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.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
