1-(4-Carboxyphenyl)-1H-imidazol-3-ium chloride dihydrate
In the crystal structure of the title compound, C(10)H(9)N(2)O(2) (+)·Cl(-)·2H(2)O, the components are linked by O-H⋯O, N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds. In the cation, the imidazole ring is oriented at a dihedral angle of 13.67 (17)° with respect to the benzene ring. In the crystal, π-π stacking occurs between nearly parallel benzene rings, which are oriented at a dihedral angle of 3.4 ...

In the crystal structure of the title compound, C(4)H(7)N(4)O(+)·Cl(-)·2H(2)O, adjacent cations are connected to one another through N-H⋯O hydrogen bonds, forming infinite chains along the b axis. These chains are further hydrogen bonded to the chloride anions and water mol-ecules, resulting in a three-dimensional network. The pyrimidine rings of adjacent mol-ecules are arranged in an anti-para...

In the title compound, C(14)H(16)N(4) (2+)·2C(7)H(5)O(6)S(-)·2H(2)O, the 3,3'-(p-phenyl-enedimethyl-ene)diimidazol-1-ium dication lies on a crystallographic inversion center. In the crystal structure, dications, anions and solvent water mol-ecules are linked via O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, and C-H⋯π inter-actions, forming a three-dimensional network containing R(2) (2)(4), R(2) (4)(1...
متن کامل9-Aminoacridin-10-ium 4-aminobenzoate dihydrate
The asymmetric unit of the title hydrated salt, C13H11N2 (+)·C7H6NO2 (-)·2H2O, consists of two independent 9-amino-acridinium cations, two 4-amino-benzoate anions and four water mol-ecules. Both 9-amino-acridinium cations are essentially planar, with maximum deviations of 0.034 (1) and 0.025 (2) Å, and are protonated at the pyridine N atoms. The 4-amino-benzoate anions are approximately planar,...
متن کامل2-(4-Methyl-2-phenylpiperazin-4-ium-1-yl)pyridine-3-carboxylate dihydrate
The title compound, C(17)H(19)N(3)O(2)·2H(2)O, is particularly useful in the preparation of mirtaza-pine, which is the active agent in a new class of anti-depressants. It crystallized as a zwitterion with two mol-ecules of water in the asymmetric unit. The crystal structure is dominated by a system of hydrogen bonds involving the positively charged N atom and both water mol-ecules.
