4,5-Dibromo-1,2-dimethyl-1H-imidazol-3-ium bromide
In the title salt, C(5)H(7)Br(2)N(2) (+)·Br(-), the cation and anion are connected by an N-H⋯Br hydrogen bond. In the crystal, there are inter-calated layers parallel to (10-2) in which bromide ions are located between the cations. Weak inter-molecular C-H⋯Br hydrogen bonds are also observed.
متن کامل3-(2-Bromobenzyl)-1-methyl-1H-imidazol-3-ium bromide
In the title compound, C(11)H(12)BrN(2) (+)·Br(-), the imidazole and phenyl rings are nearly perpendicular, making a dihedral angle of 87.71 (7)°. The crystal structure is stabilized by non-classical inter-molecular C-H⋯Br hydrogen bonds and inversion-related mol-ecules are linked through π-π inter-actions between the imidazole ring systems [centroid-centroid distance = 3.472 (6) Å].
متن کامل1,3-Diprop-2-ynyl-1H-imidazol-3-ium bromide
In the title salt, C(9)H(9)N(2) (+)·Br(-), the ethynyl groups are nearly anti-parallel to each other [the angle between the two ethynyl groups is179.7 (2)°]. No classical hydrogen bonds or π-π inter-actions are observed. The mol-ecules are linked by C-H⋯Br hydrogen bonds. The bromide anions are involved in inter-actions with three H atoms.
متن کامل2-Hydroxymethyl-1,3-dimethyl-1H-imidazol-3-ium triiodide
The crystal packing of the title salt, C6H11N2O(+)·I3 (-), can be described as consisting of alternating layers of cations and anions parallel to the (100) plane along the a-axis direction. The components are linked by O-H⋯I, C-H⋯I and C-H⋯O interactions, generating a three-dimensional network. The O atom deviates from the imidazol ring by 0.896 (2) Å.
متن کامل1H-Imidazol-3-ium-4-carboxylate
In the title compound, C(4)H(4)N(2)O(2), both imidazole N atoms are protonated and carboxyl-ate group is deprotonated, resulting in a zwitterion. The mol-ecule is essentially planar, with an r.m.s. deviation of 0.012 (1) Å. In the crystal, N-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.674 (2) Å] between the imidazole rings link the mol-ecules into a three-d...
