4-[4,5-Bis(pyridin-2-yl)-1H-imidazol-2-yl]phenol monohydrate
Abstract:
In the title hydrate, C(19)H(14)N(4)O·H(2)O, the dihedral angle between the two pyridine rings is 38.0 (2)°. The dihedral angle between the imidazole and benzene rings is 25.3 (2)°. The crystal structure is stabilized by inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds.

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.
