1-Benzyl-3,5-bis-(4-methyl-benzyl-idene)-4-oxopiperidin-1-ium chloride acetic acid monosolvate.

In the title solvated mol-ecular salt, C(28)H(28)NO(+)·Cl(-)·C(2)H(4)O(2), the central piperidinium ring of the cation adopts an envelope conformation with the N atom displaced by 0.798 (2) Å from the mean plane of the five C atoms. In the crystal, the components are linked by N-H⋯Cl and O-H⋯Cl hydrogen bonds into trimeric assemblies. C-H⋯Cl and C-H⋯π inter-actions further consolidate the packing.
