1-(2-Carboxyethyl)-3-(carboxylatomethyl)-2-ethylbenzimidazol-1-ium monohydrate
In the title compound, C14H16N2O4·H2O, three substituent groups are located on the same side of the benzimidazole ring plane. In the crystal, O-H⋯O hydrogen bonds and π-π stacking between parallel imidazole rings [centroid-centroid distance = 3.858 (4) Å] link the mol-ecules into a three-dimensional supra-molecular structure.
متن کامل3-Carboxyquinolin-1-ium-2-carboxylate monohydrate
The title compound, C(11)H(7)NO(4)·H(2)O, contains a 3-carb-oxy-quinolin-1-ium-2-carboxyl-ate (qda) zwitterion and one water mol-ecule. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion dimers, and these dimers are further connected by O-H⋯O hydrogen bonds into a three-dimensional supra-molecular architecture. In addition, π-π inter-actions occur between pyridine ...

The asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-)·2C(5)H(5)N(3)O(2)·H(2)O, comprises two symmetry-independent zwitterions, one cation, one perchlorate anion and one water mol-ecule. In the crystal, the three different types of organic entities are linked by N-H⋯O and N-H⋯N hydrogen bonds, forming undulating sheets parallel to (1-10). These sheets are in turn connected b...

In the title structure, C(7)H(9)N(3)O(2)·H(2)O, there are two formula units in the asymmetric unit. The mol-ecule is a zwitterion, containing a quaternary N atom and a deprotonated carboxyl group, with C-O distances in the range 1.256 (2)-1.266 (3) Å. The two independent mol-ecules form a hydrogen-bonded R(2) (2)(16) dimer about an approximate inversion center via N-H⋯O hydrogen bonds, with N⋯O...
متن کامل2-Amino-3-carboxypyrazin-1-ium nitrate monohydrate
In crystal structure of the title compound, C(5)H(6)N(3)O(2) (+)·NO(3) (-)·H(2)O, inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds link the cations, anions and water mol-ecules into ribbons extending in [10]. Weak inter-molecular C-H⋯O hydrogen bonds further link these ribbons into sheets parallel to (3).
