2-Cyano-2-methylsparteine Perchlorate

The cation of the title salt, C₁₇H₂₈N₃⁺.ClO₄⁻, is built up of two quinolizidine moieties and has a trans-A/B and cis-C/D configuration. All four rings adopt chair conformations. The protonation that takes place at the N16 atom and subsequent creation of an intramolecular N⁺—H...N hydrogen bond causes inversion of the N16 configuration compared with that of the free sparteine base. The perchlorate anion is disordered.
