Crystal structure of 2-(1H-imidazol-4-yl)ethanaminium chloride.

ABSTRACT: The title mol-ecular salt, C5H10N3 (+)·Cl(-), was obtained as by-product in the attempted synthesis of a histamine derivative. The terminal amino group of the starting material is protonated. The Cimidazole-C-C-N(H3)(+) group in the cation is in an anti conformation with a torsion angle of 176.22?(10)°. In the crystal, cations and anions are linked via N-H?N and N-H-Cl hydrogen bonds, forming a two-dimensional network parallel to (10-1). A single weak C-H?Cl hydrogen bond completes a three-dimensional network.

Crystal structure of 2-(1H-imidazol-3-ium-4-yl)ethanaminium dichloride, a re-determination.

Project description:The crystal structure of the title mol-ecular salt, C5H11N3 (+)·2Cl(-), was redetermined. In comparison with the previous study [Bonnet et al. (1975 ?). Bull. Soc. Fr. Mineral. Crist. 98, 208-213.], the positions of some H atoms were corrected, allowing a more accurate description of the hydrogen-bonding scheme. In addition, the absolute structure was also determined. The maximum differences in terms of bond lengths and angles between the two determinations are 0.022?Å and 1.43°, respectively. The organic cation display a anti conformation of the protonated amine function and the imidazolium ring. The dihedral angle between the imidazolium plane and the plane through the C-C-N side chain is 29.58?(3)°. In the crystal, the organic cations and Cl(-) anions are stacked alternatively into layers parallel to (100). N-H?Cl hydrogen bonds between all H atoms of the ammonium group and both N-H groups of the imidazolium ring and the Cl(-) acceptor anions lead to the linkage of organic and inorganic layers into a three-dimensional network.

1-(4-Nitro-phen-yl)-1H-imidazol-3-ium chloride.

Project description:In the title salt, C9H8N3O2(+)·Cl(-), the least-squares planes of the imidazolium and benzene rings are almost coplanar, making a dihedral angle of 4.59?(1)°. In the crystal, the chloride anion links the organic mol-ecules through N-H?Cl hydrogen bonds, forming chains that run diagonally across the bc face, which compliment strong C-H?O hydrogen bonds between neighbouring mol-ecules. These chains are connected to adjacent chains through two weak C-H?Cl inter-actions, resulting in hydrogen-bonded sheets extending along the b and c axes. The absolute structure of the title compound was determined using a Flack x parameter of 0.00?(6) and a Hooft y parameter of 0.03?(2).

Crystal structure of 1H-imidazol-3-ium 2-(1,3-dioxoisoindolin-2-yl)acetate.

Project description:The title salt, C3H5N2 (+)·C10H6NO4 (-), was obtained during a study of the co-crystallization of N'-[bis-(1H-imidazol-1-yl)methyl-ene]isonicotinohydrazide with (1,3-dioxoisoindolin-2-yl)acetic acid under aqueous conditions. The 1,3-dioxoisoindolinyl ring system of the anion is essentially planar [maximum deviation = 0.023 (2) Å]. In the crystal, cations and anions are linked via classical N-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds, forming a three-dimensional network. Weak C-H⋯π inter-actions and π-π stacking inter-actions [centroid-centroid distances = 3.4728 (13) and 3.7339 (13) Å] also occur in the crystal.

Crystal structure of 1-(1-methyl-1H-imidazol-2-yl)-4-phenyl-1H-1,2,3-triazole dihydrate.

Project description:The title compound, C12H11N5·2H2O, which crystallizes as a dihydrate, was obtained by Cu(I)-catalysed azide-alkyne cyclo-addition from 2-azido-1-methyl-imidazole and phenyl-ethyne. The dihedral angles between the central triazole ring (r.m.s. deviation = 0.004 Å) and the pendant imidazole (r.m.s. deviation = 0.006 Å) and phenyl rings are 12.3 (2) and 2.54 (19)°, respectively. In the crystal, the water mol-ecules are connected into [010] chains by O-H⋯O hydrogen bonds, while O-H⋯N hydrogen bonds connect the water mol-ecules to the organic mol-ecules, generating corrugated (100) sheets.

Crystal structure of 1-[(1-methyl-5-nitro-1H-imidazol-2-yl)meth-yl]pyridinium iodide.

Project description:In the title salt, C10H11N4O2 (+)·I(-), the asymmetric unit consists of a pyridinium cation bearning a (1-methyl-5-nitro-1H-imidazol-2-yl)methyl group at the N position and an iodide anion. The imidazole ring is quasiplanar, with a maxiumum deviation of 0.0032?(16)?Å, and forms a dihedral angle of 67.39?(6)° with the plane of the pyridinium ring. The crystal packing can be described as alternating zigzag layers of cations parallel to the (001) plane, which are sandwiched by the iodide ions. The structure features two types of hydrogen bonds (C-H?O and C-H?I), viz. cation-anion and cation-cation, which lead to the form ation of a three-dimensional network.

Crystal structure of 1-butyl-3-{2-[(indan-5-yl)amino]-2-oxoeth-yl}-1H-imidazol-3-ium chloride.

Project description:In the cation of the title mol-ecular salt, C18H24N3O+·Cl-, an intra-molecular C-H?O hydrogen bond stabilizes the almost coplanar orientation of the aromatic ring of the indane unit and the amide plane. In the crystal, the packing is dominated by inter-molecular C-H?Cl hydrogen-bonding inter-actions that result in the formation of slab-like structures propagating along [010]. The slabs are linked by weak C-H?O inter-actions, forming layers lying parallel to (100). The methyl-ene carbon atom of the indanyl substituent is disordered over two positions with a refined occupancy ratio of 0.84?(2):0.16?(2). The crystal studied was refined as a twin with matrix [1 0 0.9, 0 0, 0 0 ]; the resulting BASF value is 0.30.
