A ternary complex - in solution and in the crystal - with - charge transfer interactions is formed be the dication paraquat (MeNC5H4C5H4NMe) and two tetraphenylborate anions. This involves face-to-face and face-to-edge interactions between pyridinium rings and phenyl rings. Scarcely more than a methyl group of the flat paraquat is discernable in the illustration on the right.
