(2E)-2-[(3E)-4-Phenyl­but-3-en-2-yl­­idene]hydrazinecarboxamide

In the title compound, C11H13N3O, the phenyl ring is disordered over two sites, with occupancy factors in a 0.520 (17):0.480 (17) ratio. The dihedral angle between the ring planes of the major and minor components of the disordered ring is 12.9 (2)°. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds, forming R22(8) ring motifs. C—H⋯O, C—H⋯N and C—H⋯π inter­actions also occur
