Abstract

In the title compound, C(14)H(15)N(5)O(4), the central -C=N-N-C(=O)-C- bridge is nearly planar [maximum deviation = 0.037 (1) Å] and forms dihedral angles of 7.37 (9) and 73.33 (5)°, respectively, with the benzene and imidazole rings. The dihedral angle between the benzene and imidazole rings is 66.08 (9)°. The meth-oxy and nitro groups are nearly coplanar with the benzene and imidazole rings, respectively, with a C-O-C-C torsion angle of 5.9 (2)° and an O-N-C-C angle of -0.2 (2)°. In the crystal, mol-ecules are linked by a pair of N-H⋯O hydrogen bonds with an R(2) (2)(8) ring motif, forming an inversion dimer. The dimers are further inter-connected by C-H⋯O hydrogen bonds into a sheet parallel to the (111) plane. A C-H⋯π inter-action is also observed between the sheets.
