4,4′-(o-Phenylenedioxydimethylene)dipyridinium dinitrate
The cation of the salt, C(18)H(18)N(2)O(2) (2+)·2NO(3) (−), lies about a twofold rotation axis. The pyridinium ring is almost coplanar with the phenylene ring [dihedral angle between rings = 5.69 (9)°]. The crystal structure shows π–π stacking interactions [centroid–centroid distance = 3.70 (1) Å]...
