The structure of the OH form of a 2-hydroxyphenylimidazole was successfully observed by an X-ray crystallographic analysis of 2-(2-hydroxyphenyl)-4,5-diphenylimidazole due to the intermolecular hydrogen bonding. Two crystallographically different kinds of molecules were found in the unit cell. Each contains an intramolecular N…H-O hydrogen bond between the imidazole and hydroxyl groups [N…O: 2.528(3)Å].
