چکیده
In the title compound, C(15)H(11)NO(4), the dihedral angle between the aromatic rings is 23.8 (2)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

The complete mol-ecule of the title compound, C(16)H(12)N(2)O(4), is generated by the application of a centre of inversion. The (1,3-benzodioxol-5-yl)methyl-idene 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 π-π inter-molecular inter-actions are observed [centroid-centroid d...
