3-Amino­carbonyl­pyridinium difluoro­acetate at 123 K

In the crystal of the title compound, C(6)H(7)N(2)O(+)·C(2)HF(2)O(2) (−), 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 pyridini...

Descripción
Sumario:In the crystal of the title compound, C(6)H(7)N(2)O(+)·C(2)HF(2)O(2) (−), 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.
