2-Cyano- <i>N</i> ′-[(1 <i>E</i> )-1-(3,4-dimethoxyphenyl)ethylidene]acetohydrazide

The non-H part of the mol-ecule of the title compound, C₁₃H₁₅N₃O₃, is nearly planar, with the 2-cyano-<i>N</i>'-[(1E)-ethyl-idene]acetohydrazide moiety and the dimeth-oxy phenol ring forming a dihedral angle of 2.5 (1)°. Inter-molecular N-H⋯O, C-H⋯O and C-H⋯π inter-actions are mainly responsible for the cohesion within the crystal structure. The inter-molecular inter-actions were qu-anti-fied and analysed using Hirshfeld surface analysis, revealing that H⋯H inter-actions contribute most to the crystal packing (36.9%). The volume of the crystal voids was calculated to be 167.8 ų (13% of the unit-cell volume).
