Crystal structure of 3-(2-hydroxyethyl)-2-methylsulfanyl-6-nitro-3H-benzimidazol-1-ium chloride monohydrate
In the cation of the title hydrated molecular salt, C10H12N3O3S+·Cl-·H2O, the benzimidazolium ring system is almost planar (r.m.s. deviation = 0.006 Å) and the nitro group is inclined at an angle of 4.86 (9)° to this plane. In the crystal, C-H⋯O hydrogen bonds form centrosymmetric R22(20) dimers and these are further aggregated through N-H⋯O and O-H⋯Cl hydrogen bonds involving the water mol-ecu...
متن کاملCrystal structure of 2-nitro-N-(2-nitrophenyl)benzamide
In the title compound, C13H9N3O5, the mean plane of the non-H atoms of the central amide fragment C-N-C(=O)-C [r.m.s. deviation = 0.0442 Å] forms dihedral angles of 71.76 (6) and 24.29 (10)° with the C-bonded and N-bonded benzene rings, respectively. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds forming C(4) chains along [100]. Weak C-H⋯O contacts link the mol-ecules into (100) ...
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 کاملCrystal structure of 2-{[2-(3-phenylallylidene)hydrazin-1-yl]thiocarbonylsulfanylmethyl}pyridinium chloride
In the title salt of an S-substituted di-thio-carbazate, C16H16N3S2 (+)·Cl(-), the dihedral angles between the almost planar (r.m.s deviation = 0.005 Å) central CN2S2 residue and the terminal pyridinium and phenyl rings are 80.09 (11) and 3.82 (11)°, respectively, indicating the cation has an L-shape; the amine H and thione S atoms are syn. The conformation about each of the imine [1.376 (3) Å]...
متن کاملCrystal structure of diethyl 2-acet-oxy-2-[3-(4-nitro-phen-yl)-3-oxo-1-phenyl-prop-yl]malonate.
In the racemic title compound, C24H25NO9, the dihedral angle between the planes of the two benzene-ring systems is 80.16 (6)°, while the side-chain conformation is stabilized by a methyl-ene-carboxyl C-H⋯O hydrogen bond. Weak inter-molecular C-H⋯O hydrogen bonds form inversion dimers [graph set R 2 (2)(16)] which are linked into chains extending along a. Further C-H⋯O hydrogen bonding extends t...
