2-[2-(1H-Imidazol-3-ium-5-yl)ethyl]-3-(pyridin-2-yl)-2H-imidazo[1,5-a]pyridin-4-ium bis(perchlorate)
In the title mol-ecular salt, C(17)H(17)N(5) (+)·2ClO(4) (-), the dihedral angles between the fused-ring system and the pendant five- and six-membered heterocyclic rings are 6.4 (2) and 41.29 (19)°, respectively. The O atoms of both perchlorate anions are disordered over two sets of sites with occupancy ratios of 0.614 (8):0.386 (8) and 0.591 (7):0.409 (7). An intra-molecular C-H⋯N contact occu...
متن کامل3-(4-Carboxy-5-carboxylato-1H-imidazol-2-yl)pyridin-1-ium monohydrate
In the zwitterionic mol-ecule of the title compound, C(10)H(7)N(3)O(4)·H(2)O, one carboxyl group is deprotonated and the pyridine N atom is protonated. The pyridinium and imidazole rings form a dihedral angle of 5.23 (1)°. An intramolecular O-H⋯O hydrogen bond occurs. In the crystal, inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds link the zwitterions and water mol-ecules into sheets para...
متن کامل3-[(8-Butoxyquinolin-2-yl)methyl]-1-(pyridin-2-ylmethyl)-1H-imidazol-3-ium hexafluoridophosphate
In the cation of the title compound, C(23)H(25)N(4)O(+)·PF(6) (-), the imidazolium ring make dihedral angles of 87.20 (6) and 79.89 (5)° with the pyridine ring and the quinoline system, respectively. In the crystal, C-H⋯F and C-H⋯N hydrogen bonds are observed.
متن کاملBis[2-(1H-imidazol-2-yl-κN 3)-1H-imidazol-3-ium]silver(I) trinitrate
The synthesis of the title salt, [Ag(C(6)H(7)N(4))(2)](NO(3))(3), was carried out employing a 1:2 molar ratio of 2,2'-biimidazole and silver nitrate respectively. The cation has crystallographically-imposed C2 symmetry with the metal atom in an almost linear coordination environment [N-Ag-N = 177.01 (17)°]. The crystal structure displays N-H⋯O and C-H⋯O hydrogen-bonding inter-actions.
متن کامل1-Methyl-3-(2-oxo-2H-chromen-3-yl)-1H-imidazol-3-ium picrate
The title salt, C13H11N2O2 (+)·C6H2N3O7 (-), is the unexpected product of a domino reaction of 3-cyano-methyl-1-methyl-imidazolium chloride with salicylic aldehyde in the presence of picric acid. In the cation, the 1H-imidazole ring is twisted by 63.2 (1)° from the 2H-chromen plane. In the crystal, cations and anions are alternately stacked along the a axis through π-π stacking inter-actions be...
