R factor = 0.049; wR factor = 0.132; data-to-parameter ratio = 16.2. In the title compound, 2C15H17NOS C12H24O6, the asymmetric unit consists of one N-oxide derivative and one-half of the 18-crown-6 ether, which lies on an inversion centre. In the crown ether, the O—C—C—O torsion angles indicate a gauche conformation of the ethyleneoxy units, while the C— O—C—C torsion angles indicate planarity of these segments. In the N-oxide unit, the dihedral angle between the pyridine and benzene rings is 85.88 (12). The crystal packing is stabilized by weak C—H O hydrogen bonds and C—H interactions.
