Abstract: In the title compound, C18H22N2O42+·2NO3-, the cation is centrosymmetric. The asymmetric unit consists of one half-cation and one anion. The molecules are linked by N-HO and C-HO hydrogen bonds and by dipolar O-CO-C interactions, forming a chain of edge-fused R44(18) rings and a chain of R22(4) rings.
