4-(4-Nitro-benz-yl)pyridinium 5-nitro-salicylate.


ABSTRACT: In the title salt, C(12)H(11)N(2)O(2) (+)·C(7)H(4)NO(5) (-), the cations and anions inter-act through asymmetric cyclic pyridinium-carboxyl-ate N-H?O,O' hydrogen-bonding associations [graph set R(1) (2)(4)], giving discrete heterodimers having weak cation-anion ?-? aromatic ring inter-actions [minimum ring centroid separation = 3.7116?(9)?Å].
