摘要：

A stable 7 pi-electron system is present in the radical cation 1 which can be obtained in high yields as 1-Cl, for example, from the reaction of p-C6H4Se2Cl2 and gray selenium. 1-SO3CF3 is accessible by anionic exchange and in the solid state contains dimers comprising rings of 1 superimposed on one another. As a result of cation-anion interactions, the Coulombic repulsion of the cations is reduced.
