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.

摘要

在标题盐C24H22N4O4(2+)·2NO3(-)中，阳离子呈U形，两个异吲哚二酮环彼此倾斜60.41 (13)°，而两个外部吡啶环彼此倾斜2.77 (12)°。吡啶环与相邻异吲哚二酮环之间的二面角为71.82 (12)°和86.44 (13)°。在晶体中，每个硝酸根阴离子通过N-H⋯O氢键与一个质子化吡啶环相连。这些单元通过一系列C-H⋯O氢键相连，形成三维结构。
