Crystal structure of 4,5-bis(4-dimethylaminophenyl)-2-(4-nitrophenyl)imidazole.
A nonlinear optical chromophore, 4,5-bis(4-dimethylaminophenyl)-2-(4-nitrophenyl)imidazole, was investigated by X-ray crystallography. The study focused on coplanarity among several aromatic rings, including phenyls and imidazole. Two phenyl rings with NMe2 groups are twisted by 46.39(3) degrees from each other. However, they are twisted by 23.05(5) degrees and 46.84(3) degrees from the imidazo...
متن کاملCrystal structure of 4,5-dinitro-1H-imidazole
The title compound, C3H2N4O4, forms crystals with two mol-ecules in the asymmetric unit which are conformationally similar. With the exception of the O atoms of the nitro groups, the mol-ecules are essentially planar. In the crystal, adjacent mol-ecules are associated by N-H⋯N hydrogen bonds involving the imidazole N-H donors and N-atom acceptors of the unsaturated nitro-gen of neighboring ring...
متن کاملCrystal structure of 1-methyl-2-[(E)-2-(4-methylphenyl)ethenyl]-4-nitro-1H-imidazole
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...
متن کاملCrystal structure of 2-azido-1H-imidazole-4,5-dicarbonitrile
In the title compound, C5HN7, the nitrile and azido substituents are close to being coplanar with the central ring. Mol-ecules in the crystal are linked via an N-H⋯N hydrogen bond to a nitrile acceptor, forming a chain extending along the c-axis direction.
متن کاملCrystal structure of (E)-1-methyl-2-[2-(2-methoxphenyl)ethenyl]-4-nitro-1H-imidazole
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 bo...
