2-(Benzoyl­amino­meth­yl)pyridinium chloride

The title compound, C(13)H(13)N(2)O(+)·Cl(−), (1), was obtained as a colorless crystalline by-product during the synthesis of N-(2-pyridylmeth­yl)benzoyl­amine (2). The C—O bond length of 1.231 (2) Å in the benzoyl unit of (1) is slightly elongated in comparison with isolated C=O double bonds as also observed for (2) [1.237 (2) Å]. The N—C bond length of 1.345 (2) Å in the benzoic acid amide unit indicates the formation of an allylic O—C—N system and is very similar to the N—C bond lengths [1.345 (2) Å] of the pyridyl group. A further delocalization of charge from this allylic system into the phenyl fragment does not occur, which can be deduced from a characterisitc C—C single bond length of 1.499 (2) Å between these fragments. A dimer is formed via N—H⋯Cl hydrogen bonds. The two rings make a dihedral angle of 105.0 (2)°
