Abstract: In the title compound, C₁₉H₁₈NO⁺·I^-·0.5I₂, the I₂ molecule lies on a crystallographic center of symmetry and the cation is essentially planar and in an E configuration. The dihedral angle between the quinolinium and benzene ring systems is 4.06 (10)°. In the crystal structure, the cations are packed in an antiparallel fashion along the a axis and weak C-HO and C-HI interactions link the components of the structure into a three-dimensional network. Weak C-H interactions are also present.
