2-[(E)-4-Diethylamino-2-hydroxybenzylidene]hydrazinecarboxamide

Abstract

Two molecules make up the asymmetric unit of the title compound, C12H18N4O2, and both feature an intramolecular O—H...N hydrogen bond, which generates an S(6) ring. The diethylamino group of one of the molecules is disordered over two sets of sites in a 0.59 (2):0.41 (2) ratio. In the crystal, N—H...O hydrogen bonds link the molecules into sheets lying parallel to the ac plane and C—H...π interactions are also observed.
