Abstract The molecular and crystalstructure of 2-(2′-hydroxyphenyl)imidazole (2) and 1-methyl-2-(2′-hydroxyphenyl)imidazole (5) have been determined by X-ray analysis. Compound (2) presents a strong intramolecular hydrogen bond (IMHB) responsible for the planarity of the molecule. In both compounds the molecules form chains through NH…O (compound 2) and OH…N hydrogen bonds (compound 5) but giving
