1-Methyl-1,2,3,4-tetrahydrocarbolin-2-ium-3-carboxylate

Abstract

The title compound, C13H14N2O2, is a natural product isolated from Cicer arietinum L. (chickpea). The benzene ring and pyrrole rings display planar conformations and the piperidine ring has a half-chair conformation. Intermolecular C—H...π interactions between a methyl H atom and the pyrrole ring of an adjacent molecule are present in the crystal structure.
