In the title compound, C14H16ClN7O 2, the triazole ring carries cyano and formamidine substituents and is bound via a methylene bridge to a chloropyridine unit. There is evidence of significant electron delocalization in the triazolyl system. Intramolecular O-H ⋯ O and intermolecular C-H ⋯ N, C-H ⋯ O and O-H ⋯ N hydrogen bonds, together with strong π-π stacking interactions, stabilize the structure. © 2006 International...
