2-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.

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 کاملCrystal structure of 1,3-dicyclohexyl-4,5-dimethyl-1H-imidazol-3-ium-2-carbodithioate chloroform monosolvate
The title compound, C18H28N2S2·CHCl3, crystallizes as a zwitterion. The C-S bonds are almost equivalent, with lengths of 1.666 (3) and 1.657 (3) Å. The S-C-S bond angle is expanded to 129.54 (16)° and the N-C-N angle is reduced to the tetra-hedal value of 108.8 (2)°. In the crystal, adjacent mol-ecules are linked via C-H⋯S hydrogen bonds, forming chains along [100]. The chloro-form solvent mol-...

The title salt, C9H11N2 (+)·NO3 (-), features a planar cation (r.m.s. for 11 non-H atoms = 0.016 Å). In the crystal, N-H⋯O hydrogen bonds link nitrate and benzimidazole ions into a three-dimensional network.
متن کاملCrystal structures of the two salts 2-methyl-1H-imidazol-3-ium nitrate–2-methyl-1H-imidazole (1/1) and 2-methyl-1H-imidazol-3-ium nitrate
The title salts, C4H7N2 (+)·NO3 (-)·C4H6N2, (I), and C4H7N2 (+)·NO3 (-), (II), were obtained from solutions containing 2-methyl-imidazole and nitric acid in different concentrations. In the crystal structure of salt (I), one of the -NH H atoms of the imidazole ring shows half-occupancy, hence only every second mol-ecule is in its cationic form. The nitrate anion in this structure lies on a twof...
