C.-Y. Yu, S.-J. Yan and Z.-T. Huang

Abstract: At 294 K, the C=C(H)-C=O grouping and the imidazoline ring of the title compound, C₁₁H₁₁ClN₂O, are coplanar as a result of an intramolecular N-HO hydrogen bond and the conjugation, while the 4-chlorophenyl ring is twisted from the plane by 23.5 (2)°. Intermolecular N-HO hydrogen bonding helps to establish the crystal packing.
