2-Amino-5-methyl-pyridinium 3-hy-droxy-pyridine-2-carboxyl-ate.

ABSTRACT: In the 3-hy-droxy-picolinate anion of the title salt, C6H9N2 (+)·C6H4NO3 (-), an intra-molecular O-H?O hydrogen bond with an S(6) graph-set motif is formed, so that the anion is essentially planar, with a dihedral angle of 9.55?(9)° between the pyridine ring and the carboxyl-ate group. In the crystal, the cations and anions are linked via N-H?O hydrogen bonds, forming a centrosymmetric 2 + 2 aggregate with R 2 (2)(8) and R 4 (2)(8) ring motifs. The crystal structure also features N-H?N and weak C-H?? inter-actions.

In the 3-hy-droxy-picolinate anion of the title salt, C6H9N2 (+)·C6H4NO3 (-), an intra-molecular O-H⋯O hydrogen bond with an S(6) graph-set motif is formed, so that the anion is essentially planar, with a dihedral angle of 9.55 (9)° between the pyridine ring and the carboxyl-ate group. In the crystal, the cations and anions are linked via N-H⋯O hydrogen bonds, forming a centrosymmetric 2 + 2 aggregate with R 2 (2)(8) and R 4 (2)(8) ring motifs.

2-Amino-5-methyl-pyridinium 6-oxo-1,6-dihydro-pyridine-2-carboxyl-ate.

Project description: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 aggregate. The aggregates are further linked through weak N-H?O and C-H?O hydrogen bonds, resulting a three-dimensional network.

Project description:In the title compound, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-)·1.5H(2)O, extensive O-H?O, O-H?N, N-H?O and C-H?O hydrogen bonds, as well as ion pairing, ?-? stacking inter-actions [centroid-centroid distances = 3.4690?(8) and 3.6932?(8)?Å between aromatic rings] occur in the crystal. There are hydrogen-bonding inter-actions between water mol-ecules, which result in cyclic tetra-meric water clusters. One of the water O molecules has half occupancy. In the anion molecules, the -CO(2) and -CO(2)H groups make torsion angles of 1.73?(18) and -12.14?(18)° with respect to the ring.

Project description:In the title salt, C6H9N2 (+)·C7H5O3 (-), the anion is essentially planar, with a dihedral angle of 2.72?(17)° between the benzene ring and the carboxyl-ate group. In the crystal, the anions are connected by O-H?O hydrogen bonds, forming a 41 helical chain along the c axis. 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 with an R 2 (2)(8) ring motif. The ion pairs are further connected via another N-H?O hydrogen bond, resulting in a three-dimensional network.

Project description:The asymmetric unit of the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(5)O(3) (-), contains two cations and two anions. Both the salicylate anions contain an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring. Both the 2-amino-4-methyl-pyridine mol-ecules are protonated at their pyridine N atoms. In the crystal, both cations form two N-H?O hydrogen bonds to their adjacent anions, forming ion pairs. Further N-H?O links generate sheets lying parallel to the ab plane.
