4-Chloro-2-(6-nitro-1H-benzimidazol-2-yl)phenol N,N-dimethyl-form-amide solvate
Abstract:
In the title compound, C(13)H(8)ClN(3)O(3)·C(3)H(7)NO, the benzimidazole and benzene rings make a dihedral angle of 0.63 (11)°. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. The solvent mol-ecule is hydrogen-bonded to the benzimidazole mol-ecule by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, generating an R(1) (2)(7) ring motif. In the crystal, the mol-ecules are arranged into parallel layers perpendicular to the c axis and stabilized by weak π-π inter-actions [centroid-centroid distances in the range 3.4036 (18)-3.5878 (16) 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.
