title: 4-[2-(4-But-oxy-phen-yl)ethen-yl]-1-methyl-pyridinium tosylate.
abstract: In the title mol-ecular salt, C18H22NO(+)·C7H7O3S(-), the dihedral angle between the aromatic rings in the cation is 10.00 (9)°; its alkyl side chain adopts an extended conformation. In the crystal, weak C-H⋯O and π-π [centroid-centroid distance = 3.7658 (17) Å] inter-actions link the components, generating a three-dimensional network.
