1-(2,4-Di-nitro-phen-yl)-2-[(E)-(3,4,5-tri-meth-oxy-benzyl-idene)]hydrazine.

ABSTRACT: Mol-ecules of the title compound, C16H16N4O7, are not planar with a dihedral angle of 5.50?(11)° between the substituted benzene rings. The two meta-meth-oxy groups of the 3,4,5-tri-meth-oxy-benzene moiety lie in the plane of the attached ring [Cmeth-yl-O-C-C torsion angles -0.1?(4)° and -3.7?(3)°] while the para-meth-oxy substituent lies out of the plane [Cmeth-yl-O-C-C, -86.0?(3)°]. An intra-molecular N-H?O hydrogen bond involving the 2-nitro substituent generates an S(6) ring motif. In the crystal structure, mol-ecules are linked by weak C-H?O inter-actions into screw chains, that are arranged into a sheet parallel to the bc plane. These sheets are connected by ?-? stacking inter-actions between the nitro and meth-oxy substituted aromatic rings with a centroid-centroid separation of 3.9420?(13)?Å. C-H?? contacts further stabilize the two-dimensional network.
