Abstract: 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].
