The crystal structure of the title compound, was reported previously from Weissenberg photographic data with R = 0.127. It has now been redetermined, providing a significant increase in the precision of the derived geometric parameters. The crystal packing is governed by N--HO hydrogen bond-type intermolecular interactions, forming infinite one-dimensional chains with graph-set notation C(4), R22(8) and R24(8).enMonoclinic crystal systemHydrogen bondCrystal structureCrystallographyIntermolecular forceChemistryCrystal (programming language)Moleculearticle
