1-(2,4-Di­nitro­phen­yl)-2-[(E)-2,4,5-tri­meth­oxy­benzyl­idene]hydrazine

The title compound, C(16)H(16)N(4)O(7), is close to being planar, with a dihedral angle of 3.15 (11)° between the benzene rings. The meth­oxy groups at the ortho- and para-positions of the 2,4,5-tri­meth­oxy­phenyl group are almost coplanar with the ring [deviations of the C atoms = 0.017 (2) and −0.025 (2) Å, respectively], whereas the meta-meth­oxy group deviates slightly [C-atom displacement = 0.162 (2) Å]. Both the ortho- and para-nitro groups are close to being coplanar with their attached ring [dihedral angles = 7.81 (12) and 8.56 (11)°, respectively]. An intra­molecular N—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, inversion dimers linked by pairs of N—H⋯O hydrogen bonds involving the same H atom as the intra­molecular bond generate R (2) (2)(12) loops. The dimers are linked by weak C—H⋯O inter­actions into sheets parallel to the (10-4) plane and the sheets are stacked by π–π inter­actions, with a centroid–centroid distance of 3.5974 (14) Å.
