title: Bis{(E)-3-[(diethyl-methyl-ammonio)meth-yl]-N-[3-(N,N-dimethyl-sulfamo-yl)-1-methyl-pyridin-4-yl-idene]-4-methoxy-anilinium} tetra-iodide penta-hydrate.
abstract: The title compound, 2C(21)H(34)N(4)O(3)S(2+)·4I(-)·5H(2)O, was prepared exclusively as the E isomer by methyl-ation of the corresponding N-phenyl-pyridin-4-amine. There are two symmetry-independent mol-ecules 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)°.
