Key indicators: single-crystal X-ray study; T = 150 K; mean (C-C) = 0.002 Å; R factor = 0.046; wR factor = 0.112; data-to-parameter ratio = 16.2.In the title molecule, C 18 H 15 N 3 O 2 , the dihedral angle between the quinoline and benzimidazole ring systems is 23.57 (5) . The C atoms of the methoxy groups are both close to being coplanar with their attached ring systems [deviations = 0.193 (2) and À0.020 (2) Å ]. An intramolecular N-HÁ Á ÁO hydrogen bond closes an S(6) ring. In the crystal, N-HÁ Á ÁN hydrogen bonds link the molecules into C(4) chains propagating in [010]. Weak C-HÁ Á Á interactions also occur. Related literature ExperimentalCrystal data

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

In the asymmetric unit of the title compound, C13H13N3O3, the 2-(2-methoxphen­yl)ethenyl unit is connected to the methyl-nitro­imidazole 1-methyl-4-nitro-1H-imidazole moiety. The mol­ecule 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 inter­molecular C—H⋯O hydrogen bonding, resulting in the formation of an infinite three-dimensional network linking these layers. Strong π–π stacking inter­actions 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.
