Crystal structure of 4,4'-[(1,3,5,7-tetra-oxo-1,3,3a,4,4a,5,7,7a,8,8a-deca-hydro-4,8-etheno-pyrrolo-[3,4-f]iso-indole-2,6-di-yl)bis-(methyl-ene)]bis-(pyridin-1-ium) dinitrate.

ABSTRACT: In the title salt, C24H22N4O4 (2+)·2NO3 (-), the cation is U-shaped with the two iso-indole dione rings inclined to one another by 60.41 (13)°, while the two outer pyridine rings are inclined to one another by 2.77 (12)°. The dihedral angles between the pyridine ring and the adjacent iso-indole dione ring are 71.82 (12) and 86.44 (13)°. In the crystal, each nitrate anion is linked to a protonated pyridine ring by N-H⋯O hydrogen bonds. These units are linked by a series of C-H⋯O hydrogen bonds, forming a three-dimensional structure.
