2,2′,4,4′-Tetramethyl-7,7′-diazenediylbis(1,8-naphthyridin-1-ium) bis(perchlorate)

Abstract

In the title salt, C20H20N62+·2ClO4−, the cation is disposed about a center of symmetry at the mid-point of the N=N bond. The 1,8-naphthyridine systems are planar and the ten atoms have a mean deviation of 0.01 Å from the least-squares plane. The two planar 1,8-naphthyridine units are parallel but extend in opposite directions from the diazene bridge. The 1,8-naphthyridine aminium groups interact with perchlorate O atoms through N—H...O hydrogen bonds.
