2,2′-[2,3,5,6-Tetra­methyl-p-phenyl­ene­bis(methyl­enethio)]bis­(pyridine N-oxide)

Mol­ecules of the title compound, C(22)H(24)N(2)O(2)S(2), lie across centres of inversion. The two thio­pyridine N-oxide groups adopt a stepped trans configuration with respect to the benzene ring, by virtue of the symmetry. The oxopyridinium ring forms a dihedral angle of 79.9 (2)° with the benzene...

Sumario:Mol­ecules of the title compound, C(22)H(24)N(2)O(2)S(2), lie across centres of inversion. The two thio­pyridine N-oxide groups adopt a stepped trans configuration with respect to the benzene ring, by virtue of the symmetry. The oxopyridinium ring forms a dihedral angle of 79.9 (2)° with the benzene ring. The crystal structure is stabilized by a strong π–π inter­action between the pyridinium rings of adjacent mol­ecules [ring centroid–centroid distance = 3.464 (3) Å].
