4-Carbamoylpyridin-1-ium 2,2,2-trichloro­acetate

In the asymmetric unit of the title salt, C(6)H(7)N(2)O(+)·C(2)Cl(3)O(2) (−), there are two crystallographic independent ion pairs. The amide groups of the 4-carbamoylpyridin-1-ium ions are slightly twisted out of the plane of the aromatic ring with C—C—C—N torsion angles of 8.8 (9)° and 4.6 (8)°. I...

description In the asymmetric unit of the title salt, C(6)H(7)N(2)O(+)·C(2)Cl(3)O(2) (−), there are two crystallographic independent ion pairs. The amide groups of the 4-carbamoylpyridin-1-ium ions are slightly twisted out of the plane of the aromatic ring with C—C—C—N torsion angles of 8.8 (9)° and 4.6 (8)°. In the crystal, the 4-carbamoylpyridin-1-ium ion is N—H⋯O hydrogen bonded to the trichloro­acetate ion via the pyridinium unit and amide group. Layers parallel to the ac plane are formed due to the N—H⋯O hydrogen bonding of the adjacent amide groups of 4-carbamoylpyridin-1-ium ions. Weak C—H⋯O inter­actions also occur.
