Abstract: The title compound, 2C₂₁H₃₄N₄O₃S²⁺·4I^-·5H₂O, was prepared exclusively as the E isomer by methylation of the corresponding N-phenylpyridin-4-amine. There are two symmetry-independent molecules in the asymmetric unit with no significant differences in bond lengths and angles. The aromatic rings are not coplanar with the pyridin-4-imine groups, as indicated by the C-N-C-C torsion angles of 47.7 (7) and 132.6 (5)°.
