✦ Synopsis

The title compound, C~11~H~16~N~2~
^2+^·2Cl^−^·H~2~O, is a novel conformationally constrained tricyclic analogue of nicotine, in which the pyridine and pyrrolidine rings of the latter are bridged by a CH~2~ group. As result of this bridge, these two rings are no longer approximately perpendicular as in various salts of nicotine.

At 150 K, the tricyclic core of the title compound, C 34 H 31 NO 3 , is close to planar. One of the three 4-methoxyphenyl substituents is twisted out of the plane of the tricyclic core due to steric congestion.
