2-Amino-5-methylpyridinium 6-oxo-1,6-dihydropyridine-2-carboxylate
The anion of the title salt, C(6)H(9)N(2) (+)·C(6)H(4)NO(3) (-), undergoes an enol-to-keto tautomerism during the crystallization. In the crystal structure, the cation and anion are held together by a relatively short N-H⋯O hydrogen bond, and the two anions are further connected to each other by a pair of N-H⋯O hydrogen bonds with an R(2) (2)(8) ring motif, thus forming a centrosymmetric 2 + 2 ...

In the crystal structure of the title salt, C(5)H(6)BrN(2) (+)·C(6)H(4)NO(3) (-)·H(2)O, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The ion pairs are further connected via O-H⋯O, N-H⋯O, N-H⋯Br and C-H⋯O hydrogen bonds, forming a two-dimensional networ...

The title compound, C11H9N5OS2, a 1-thio-phen-2-yl-methyl-ene-amino-pyrimidine derivative, displays an essentially planar C-NH2 group. The conformation across the N=C bond linking the pyrimidine and thienyl groups is E. The pyrimidine and thienyl ring systems subtend an inter-planar angle of 42.72 (5)°. In the crystal, mol-ecules are linked by N-H⋯Nnitrile and N-H⋯O=C hydrogen bonds, forming ch...

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...
