2-[2-(2-Pyridyl)ethyl]isoindolinium perchlorate

In the title salt, C15H17N2 +·ClO4 −, the isoindoline N atom is protonated and an intramolecular N—H⋯N hydrogen bond occurs. In the crystal, N—H⋯O and numerous weak C—H⋯O interactions occur between the cation and anion. The O atoms of the perchlorate anion are disordered over four sets of sites with occupancies of 0.438 (4), 0.270 (9), 0.155 (8) and 0.138 (5).
