Abstract

The title compound, C\sb 18H\sb 23N\sb 2\sp +⋅Cl\sp -}}, is a non-merohedrally twinned salt domains 0.9288(3) and 0.0712(3) which crystallizes with four independent cation{--}anion pairs in the asymmetric unit. The seven-membered ring in each of the cations adopts a boat conformation, thus creating a butterfly effect within the ring system. The average value of the dihedral angle between the two aromatic rings in the four cations is 57.1(1){$^\circ$}. The crystal packing is stabilized only slightly by a collection of inter{\-}mediate N{---}H{$\cdots$}Cl hydrogen-bonding inter{\-}actions, which produce a weak, but cooperative, infinite, one-dimensional, inter{\-}molecular hydrogen-bond network along the {\it a} axis. A MOPAC PM3 computational calculation gives support to these observations.
