Crystal Structure of N-n-Propylalcohol-2-oxo-5-nitro-1-benzylidene-methylamine

Abstract

The title compound, C<inf>10</inf>H<inf>12</inf>N<inf>2</inf>O<inf>4</inf>, 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 P2<inf>1</inf>/c with the following unit-cell parameters: a = 10.953(2)Å, β = 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.
