5-Amino-6-methylquinolin-1-ium hydrogen malonate–malonic acid (2/1)
The asymmetric unit of the title compound, 2C10H11N2(+)·2C3H3O4(-)·C3H4O4, consists of one 5-amino-6-methyl-quinolin-1-ium cation, one hydrogen malonate (2-carb-oxy-acetate) anion and one-half mol-ecule of malonic acid which lies on a twofold rotation axis. The quinoline ring system is essentially planar, with a maximum deviation of 0.062 (2) Å for all non-H atoms. In the anion, an intra-molecu...

In the title salt, C(4)H(5)ClN(3) (+)·C(4)H(3)O(4) (-), the 2-amino-5-chloro-pyrimidinium cation is protonated at one of its pyrimidine N atoms. In the roughly planar (r.m.s. deviation = 0.026 Å) hydrogen malate anion, an intra-molecular O-H⋯O hydrogen bond generates an S(7) ring. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O...

The asymmetric unit of the title salt, C10H11N2 (+)·C4H5O4 (-), consists of two independent 5-amino-6-methyl-quinolin-1-ium cations and two 3-carb-oxy-propano-ate anions. Both cations are protonated at the pyridine N atoms and are essentially planar, with maximum deviations of 0.026 (3) and 0.016 (2) Å. In the crystal, the cations and anions are linked via N-H⋯O and O-H⋯O hydrogen bonds, formin...

In the title molecular salt, C(7)H(6)N(3)O(2)S(+)·HSO(4) (-), the 2-amino-6-nitro-1,3-benzothia-zole ring system is essentially planar [mean deviation = 0.0605 (4) Å]. In the crystal, N-H⋯O and O-H⋯O hydrogen-bonding inter-actions result in a layer motif.
متن کامل5-Amino-1H-pyrazol-2-ium hydrogen succinate
In the cation of the title salt, C3H6N3 (+)·C4H5O4 (-), the protonated pyrazolium ring is planar (r.m.s. deviation = 0.012 Å). An intra-molecular C-H⋯O hydrogen bond occurs in the anion. In the crystal, N-H⋯O hydrogen bonds and a weak C-H⋯O inter-action between the cations and anions form two sets of R 2 (2)(8) graph-set ring motifs. Inter-molecular O-H⋯O hydrogen bonds between these lead to a ...
