Abstract
The asymmetric unit of the title salt, C36H32N2
2+�-
2C6H4ClO3S�, consists of one anion and one half-cation, the
other half being generated by inversion symmetry. The
dihedral angle between the pyridinium ring and the napthalene
ring system in the asymmetric unit is 42.86 (6)�. In the
crystal, cations and anions are linked by weak C—H...O
interactions into chains along [010]. Adjacent chains are
further arranged in an antiparallel manner into sheets parallel
to the bc plane. �–� interactions are observed involving the
cations, with centroid–centroid distances of 3.7664 (8) and
3.8553 (8) A ° .
