Abstract: The complete molecule of the title compound, C16H12N2O4, is generated by the application of a centre of inversion. The (1,3-benzodioxol-5-yl)methylidene fused-ring system is approximately planar (r.m.s. deviation = 0.020 Å) and is essentially coplanar with the central hydrazine group [dihedral angle = 5.08 (9)°]. Weak - intermolecular interactions are observed [centroid-centroid distance = 3.8553 (8) Å], providing some packing stability.
