چکیده
In the structure of the title salt, C(6)H(9)N(2) (+)·C(7)H(6)NO(2) (-), the 4-amino-benzoate anions are linked to adjacent anions and 2-amino-4-methyl-pyridinium cations via N-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular structure. The crystal structure also shows a weak C-H⋯O hydrogen bond between adjacent anions. Within the 4-amino-benzoate anion, the carboxyl-ate group is twisted by 14.0 (4)° with respect to the benz-ene ring.

In the title compound, C(6)H(9)N(2) (+)·C(7)H(6)NO(2) (-), the H atom of the N-H group and an H atom of the 2-amino group from the cation are involved in inter-molecular N-H⋯O hydrogen bonds with the O atoms of the carboxyl-ate group of the anion, forming an R(2) (2)(8) ring motif. These ring motifs are, in turn, connected by further N-H⋯O hydrogen bonds, forming a two-dimensional network. The ...

The title compound, (C(6)H(9)N(2))(2)[CuCl(4)], contains a distorted tetra-hedral [CuCl(4)](2-) anion and two protonated amino-pyridinium cations. The geometries of the protonated amino-pyridinium cations reveal amine-imine tautomerism. The crystal packing is influenced by N-H⋯Cl and C-H⋯Cl hydrogen bonds and π-π stacking inter-actions [centroid-centroid distances = 3.635 (4) and 3.642 (4)°].

In the title salt, C(3)H(5)N(2) (+)·C(7)H(6)NO(2) (-), the carboxyl-ate group of the 4-amino-benzoate anion forms a dihedral angle of 13.23 (17)° with respect to the benzene ring. There are N-H⋯O hydrogen-bonding inter-actions between the anion and cation, and weak inter-molecular C-H⋯O contacts with carboxyl-ate O-atom acceptors of the 4-amino-benzoate anion result in extended three-dimensiona...
