2,2′-(p-Phenylene)bis(4,5-dihydro-1H-imidazol-3-ium) bis(3-nitrobenzoate)
In the title compound, C(12)H(16)N(4) (+)·2C(7)H(4)NO(4) (-), the complete 2,2'-(p-phenyl-ene)bis-(4,5-dihydro-1H-imidazol-3-ium) (bib) dication is generated by crystallographic inversion symmetry. The bib cations reside on crystallographic inversion centers, which coincide with the centroids of the respective benzene rings. In the cation, the imidazole ring adopts an envelop conformation with ...

In the cation of the title compound, C(12)H(15)N(4) (+)·C(7)H(6)NO(2) (-), the benzene ring makes dihedral angles of 30.51 (9) and 25.64 (9)° with the imidazole and imidazolinium rings, respectively. In the crystal, inter-molecular N-H⋯O and N-H⋯N hydrogen-bonding inter-actions link the mol-ecules into a three-dimensional network.

In the cation of the title compound, C(22)H(19)N(2) (+)·NO(3) (-), the N atom in the 3-position of the imidazole is protonated. The three pendant aromatic rings are twisted from the plane of the imadazolium ring by dihedral angles of 38.1 (1), 43.74 (9) and 20.4 (1)°. In the crystal structure, N-H⋯O and N-H⋯(O,O) hydrogen bonds link the mol-ecules to form an infinite one-dimensional chain paral...

In the title compound, C(22)H(19)N(2) (+)·ClO(4) (-), the three pendant aromatic rings are twisted from the plane of the imidazolium ring by dihedral angles of 17.3 (2), 65.7 (2) and 3.4 (2)°. In the crystal structure, N-H⋯O and N-H⋯(O,O) hydrogen bonds link the ions, forming a ribbon-like structure along the a axis.
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...
