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.

2-Amino-5-methyl-pyridinium 4-carb-oxy-butano-ate.

Project description: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 hydrogen bonds. The crystal structure is further stabilized by weak C-H?O inter-actions.

Project description:In the structure of the title compound, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (-), the cis anions associate through head-to-tail carb-oxy-lic acid-carboxyl O-H?O hydrogen bonds [graph set C(7)], forming chains which extend along c and are inter-linked through the carboxyl groups, forming cyclic R(2) (2)(8) associations with the pyridinium and an amine H-atom donor of the cation. Further amine-carboxyl N-H?O inter-actions form enlarged centrosymmetric rings [graph set R(4) (4)(18)] and extensions down b, giving a three-dimensional structure.

The anion possesses an eclipsed conformation, with the torsion angle φ (Csubst-Cpcent-Cpcent- Csubst) equal to 66.0°. The conformations of other 1'-carb-oxy-ferrocene-1-carboxyl-ate monoanions are compared and analyzed on the basis of literature data.

Project description: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⋯π inter-actions.

The N-H⋯O hydrogen bond between the donor acridinium cation and the carboxyl-ate acceptor is particularly strong. The average separation between the π-stacked acridinium planes is 3.42 (3) Å.

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.

Acridin-10-ium 6-carb-oxy-pyridine-2-carboxyl-ate.

Project description:The title compound, C(13)H(10)N(+)·C(7)H(4)NO(4) (-), consists of a protonated acridinium cation and a 6-carb-oxy-pyridine-2-carboxyl-ate monoanion. The carboxyl-ate group of the anion appears to be delocalized on the basis of the nearly equivalent C-O bond lengths. In the crystal, the anions are connected by strong O-H?O hydrogen bonds, forming chains along the b axis. The acridinium cations are linked to the anionic chains by strong N-H?O hydrogen bonds between the carboxyl-ate group of the anion and the N-H group of the cation. Along the b axis, successive chains stack in opposite directions. Weak inter-molecular C-H?O hydrogen bonds further stabilize the crystal structure.
