Pyridinium 5-nitrothiophene-2-carboxylate
The anion of the title compound, C(5)H(6)N(+)·C(5)H(2)NO(4)S(-), is approximately planar, with the carboxyl-ate and nitro group planes forming dihedral angles of 7.5 (3) and 3.5 (3)°, respectively, with the thio-phene ring. In the crystal structure, the cations and anions are linked into a two-dimensional network parallel to (011) by N-H⋯O and C-H⋯O hydrogen bonds.

The title compound, C(12)H(10)N(2)O(2)·H(2)O, crystallizes as a zwitterion in which the pyridine N atom is protonated and the carb-oxy -OH group is deprotonated. The benzene and pyridinium rings are inclined with a dihedral angle of 6.63 (5)° between them. In the crystal, inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions link adjacent mol-ecules into a two-dimensional double layere...

In the title compound, C(6)H(6)N(5) (+)·Cl(-), the pyridinium and tetra-zole rings are essentially coplanar. The pyridine N atoms are protonated. In the crystal structure, mol-ecules are connected via N-H⋯Cl, C-H⋯Cl, C-H⋯N and N-H⋯N hydrogen bonds into layers that are parallel to the (001) plane. There are two crystallographically independent mol-ecules in the asymmetric unit which are located ...
متن کامل2-Amino-5-(1H-tetrazol-5-yl)pyridinium chloride
In the title salt, C(6)H(7)N(6) (+)·Cl(-), there are two organic cations with similar conformations and two chloride anions in the asymmetric unit. The pyridine and tetra-zole rings are essentially coplanar in each cation, with dihedral angles of 4.94 (15) and 5.41 (14)°. The pyridine N atoms are protonated. The crystal packing is stabilized by N-H⋯N and N-H⋯Cl hydrogen bonds, forming an infini...
