摘要：

The structure of the dark red title salt shows a distorted planar quinone ring with CC bonds of 133, 147 and 153 pm length and distorted pyridine rings twisted by 56-degrees or 63-degrees with ipso angles of 116-degrees; it can be largely rationalized both by structure comparison with other p-benzoquinone derivatives or pyridinium salts and by MNDO calculations, which suggest that an extensive delocalization of the four positive charges may contribute to its stability.
