In the mol­ecule of the title compound, C16H18N4O4, the dihedral angle between the mean planes of the two benzene rings is 56.76 (5)°. The crystal structure reveals extensive inter­molecular hydrogen bonds between carbonyl O atoms and primary amines, as well as between primary and secondary amines of hydrazide, forming rings of R 2 2(10) and R 2 2(6) motifs, respectively. The structure is further stabilized by intra­molecular and non-classical hydrogen bonds of the types N—H⋯O and C—H⋯O, respectively. The structure does not show any π–π inter­actions.
