Crystal packing of two 5-substituted 2-methyl-4-nitro-1H-imidazoles.
Infinite chains connected by N-H...N hydrogen bonding form the primary packing motif in two closely related 4-nitroimidazole derivatives, viz. 5-bromo-2-methyl-4-nitro-1H-imidazole, C(4)H(4)BrN(3)O(2), (I), and 2-methyl-4-nitro-1H-imidazole-5-carbonitrile, C(5)H(4)N(4)O(2), (II). These chains are almost identical, even though in (II) there are two symmetry-independent molecules in the asymmetri...
متن کامل2-Methyl-5-nitro-1H-benzimidazole monohydrate
In the title compound, C(8)H(7)N(3)O(2)·H(2)O, the 2-methyl-5-nitro-1H-benzimidazole mol-ecule, excluding the methyl H atoms, is approximately planar, with a maximum deviation of 0.137 (1) Å. The crystal structure is stabilized by water mol-ecules via N-H⋯O(water), O(water)-H⋯O and O(water)-H⋯N hydrogen bonds, forming sheets parallel to the (100) plane. A short inter-molecular contact between t...
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 (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...
متن کاملNitroimidazoles XIII. Synthesis of Substituted (1-Methyl-5-Nitro-2-Imidazolyl) Isoxazoles
The beta0diketone derivatives of nitroimidazole were synthesized from the reaction of magnesium salt of beta-ketoaccids 3 with imidazolide 4. The raction of beta-diketones with hydroxylamine hydrochloride afforded either the isoxazoles or the 5-hydroxyl-2-isoxazolines.
