2,2′-[o-Phenylenebis(methylenethio)]bis(pyridine N-oxide)

In the title compound, C18H16N2O2S2, the benzene ring makes dihedral angles of 7.41 and 86.59° with the two outer pyridine N-oxygen rings. Two short intramolecular C—H...S contacts occur. The crystal packing is stabilized by C—H...O hydrogen bonds, C—H...π interactions and weak π–π staking interactions [centroid–centroid distance 3.7596 (7) ].
