2-Amino-4-methylpyridinium 2-hydroxy-3,5-dinitrobenzoate
In the anion of the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the two nitro groups are twisted from the attached benzene ring with dihedral angles of 27.36 (10) and 4.86 (11)°. The anion is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, the cations and anions are linked by N-H⋯O and C-H⋯O inter-actions and are furthe...

In the title salt, C(6)H(9)N(2) (+)·C(5)H(7)O(4) (-), the 2-amino-5-methyl-pyridinium cation is essentially planar, with a maximum deviation of 0.008 (1) Å. In the crystal, the protonated N atom and the 2-amino group are hydrogen bonded to the carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The 4-carb-oxy-butano-ate anions are linked via O-H⋯O hydroge...

In the crystal structure of the title compound, C(4)H(10)NO(+)·C(8)H(10)NO(4)S(-), the components are linked by N-H⋯O hydrogen bonds, forming a centrosymmetric 2:2 aggregate. The aggregates are further connected by N-H⋯O hydrogen bonds between the anions, forming a double-tape structure along the a axis.
متن کامل2-Amino-5-methylpyridinium 4-nitrobenzoate
In the title compound, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-), the nitro group of the 4-nitro-benzoate anion is twisted by 6.2 (2)° from the attached ring. In the crystal structure, the cations and anions are linked via strong N-H⋯O and weak C-H⋯O hydrogen bonds, forming a three-dimensional network.
متن کامل2-Amino-5-chloropyridinium 4-hydroxybenzoate
In the title salt, C(5)H(6)ClN(2) (+)·C(7)H(5)O(3) (-), the carboxyl-ate mean plane of the 4-hydroxy-benzoate anion is twisted by 7.16 (9)° from the attached ring. In the crystal structure, the cations and anions are linked via O-H⋯O and N-H⋯O hydrogen bonds, as well as C-H⋯O contacts, forming a three-dimensional network. In addition, weak π-π inter-actions involving the benzene and pyridinium ...
