Crystal structure of N-n-propylalcohol-2-oxo-5-nitro-1-benzylidene-methylamine

Abstract

The title compound, C10H12N2O4, adopts the keto-amine tautomeric form and displays two intramolecular N-H···O hydrogen bonds. The keto-amine structure is favored by through-molecule conjugation between the hydroxyl O atom and the imine N atom. The title compound crystallizes in the monoclinic space group P21/c with the following unit-cell parameters: a = 10.953(2)Å, ? = 5.5272(6)Å, c = 18.754(4)Å, b = 108.306(16)° and V = 1077.9(3)Å3. The crystal structure of this compound contains two molecules in an asymmetric unit, and each molecule exists as part of an O-H···O hydrogen-bonded centrosymmetric dimer. 2009 © The Japan Society for Analytical Chemistry.
