Abstract:
The asymmetric unit of the title co-crystal, C(20)H(16)N(2)·C(18)H(20)O(2), contains one mol-ecule of 4,4'-(cyclo-hexane-1,1-di-yl)diphenol (in which the cyclo-hexane ring adopts a chair conformation) and one mol-ecule of 1-benzyl-2-phenyl-1H-benzimidazole, which are paired through an O-H⋯N hydrogen bond. These pairs are further linked by inter-molecular O-H⋯O hydrogen bonds into chains along [010]. Weak inter-molecular C-H⋯O and C-H⋯π inter-actions further consolidate the crystal packing. The dihedral angles between the pendant phenyl rings and the benzimidazole ring are 86.9 (2) and 43.1 (2)°.

In cyclohexane, the substituents can occupy different positions generating distinct isomers.
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...

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...
Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...
