چکیده
In the asymmetric unit of the title compound, C13H13N3O3, the 2-(2-methoxphen-yl)ethenyl unit is connected to the methyl-nitro-imidazole 1-methyl-4-nitro-1H-imidazole moiety. The mol-ecule is quasi-planar and the planes of the two rings form a dihedral angle of 0.92 (11)°. The crystal packing can be described as layers parallel to the (011) plane, stabilized by inter-molecular C-H⋯O hydrogen bonding, resulting in the formation of an infinite three-dimensional network linking these layers. Strong π-π stacking inter-actions are observed, viz. benzene-benzene, imidazole-imidazole and benzene-imidazole rings, with centroid-centroid distances of 3.528 (2), 3.457 (2) and 3.544 (2) Å, respectively. Intensity statistics indicated twinning by non-merohedry, with refined weighs of the twin components of 0.3687:0.6313.

In the title mol-ecule, C13H13N3O2, the planes of the benzene and imidazole rings form a dihedral angle of 7.72 (5)°. In the crystal, mol-ecules are linked by weak C-H⋯N and C-H⋯O hydrogen bonds, forming layers parallel to (100). A weak C-H⋯π inter-action connects these layers into a three-dimensional network. A π-π stacking inter-action, with a centroid-centroid distance of 3.5373 (9) Å, is al...
