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

ABSTRACT: 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.

2-(4-Carb-oxy-piperidinium-1-yl)pyridine-3-carboxyl-ate.

Project description:The title compound, C(12)H(14)N(2)O(4), crystallizes as a zwitterion. A negative charge is delocalized in the deprotonated carboxyl group attached to the pyridine ring. The piperidine N atom accepts a proton and the ring is transformed into a piperidinium cation. There is an intra-molecular N-H⋯O hydrogen bond between the protonated NH and a carboxyl-ate O atom. In the crystal, an O-H⋯O hydrogen bond between the carboxyl group and the carboxyl-ate O atom of another mol-ecule generates a helix along the b axis.

9-Amino-acridin-10-ium 4-amino-benzo-ate dihydrate.

Project description:The asymmetric unit of the title hydrated salt, C13H11N2 (+)·C7H6NO2 (-)·2H2O, consists of two independent 9-amino-acridinium cations, two 4-amino-benzoate anions and four water mol-ecules.

The 4-amino-benzoate anions are approximately planar, with dihedral angles of 9.16 (19) and 5.4 (2)° between the benzene ring and the carboxyl-ate group. In the crystal, the two independent anions are connected by N-H⋯O hydrogen bonds, forming a layer parallel to (100). The layers are connected through the cations by N-H⋯N and N-H⋯O hydrogen bonds.
