(1S,2S,4S,5S)-2,5-Dibenzyl-1,4-diazo­niabicyclo­[2.2.2]octane dichloride methanol solvate

In the cation of the title compound, C₂₀H₂₆N₂²⁺·2Cl^-·CH₄O, there is an approximate twofold rotation axis. All the four chiral centers are in the S configuration. All three six-membered rings in the central part of the cation adopt a boat conformation. Both chloride anions and the O atom in the solvent mol­ecule form hydrogen bonds with the cation, resulting in a chain along [010].
