3-Aminocarbonylpyridinium difluoroacetate at 123 K

Abstract

In the crystal of the title compound, C6H7N2O+·C2HF2O2−, the cation adopts a catemeric N—H...O hydrogen-bonded chain motif involving the carboxamide group, with two further N—H...O hydrogen bonds connecting the cations to adjacent difluoroacetate anions via the carboxamide and pyridinium N atoms. The carboxamide group of the nicotinamidium ion is twisted by 32.3 (6)° from the pyridine ring plane. A number of C—H...O and C—H...F interactions consolidate the packing.
