description In the crystal structure of the title 1:1 co-crystal, C6H7N2O+·C2Cl3O2−·C6H6N2O, the amide groups of the 4-carbamoylpyridin-1-ium ion and the isonicotinamide molecule are twisted out of the plane of the aromatic ring with C—C—C—N torsion angles of 21.5 (4) and −33.5 (4)°, respectively. The 4-carbamoylpyridin-1-ium and isonicotinamide amide groups form R22(8) hydrogen-bonded dimers via N—H...O=C interactions. The two remaining amide H atoms (i) link dimers via the cation to an isonicotinamide and (ii) from the isonicotinamide to a trichloroacetate anion. The pyridinium H atom also forms an N—H...O hydrogen bond with the trichloroacetate anion. Due to the extended hydrogen bonding, including C—H...O and C—H...Cl interactions, all components in the structure aggregate into a three-dimensional supramolecular framework.
