title: 2,2'-[o-Phenylenebis(methylenethio)]bis(pyridine N-oxide).
abstract: In the title compound, C(18)H(16)N(2)O(2)S(2), 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 inter-actions and weak π-π staking inter-actions [centroid-centroid distance 3.7596 (7) Å].
