N′-[1-(4-Nitrophenyl)ethylidene]acetohydrazide

The title compound, C11H14ClN2O, was prepared by the reaction between p-chloro­hypnone and acetohydrazide. The asymmetric unit consists of two crystallographically independent mol­ecules. Symmetry-related mol­ecules form two N—H⋯O and weak C—H⋯O hydrogen-bonded chains. Weak inter­actions between the dimers stabilize the crystal packing.
