Abstract

In the title compound, C19H21N2O2+·C2H3O2−, the 1H-indole ring system is essentially planar [maximum deviation = 0.0257 (14) Å] and forms a dihedral angle of 87.92 (7) Å with the benzene ring attached to the tetra­hydro­pyridinium fragment. The tetra­hydro­pyridinium ring adopts a half-chair conformation. In the crystal, cations and anions are linked by inter­ionic N—H⋯O, C—H⋯O and C—H⋯N hydrogen bonds into chains along the a axis.
