An Unprecedented Hexapotassium-Hexamagnesium 24-Membered Macrocyclic Amide: A Polymetallic Cationic Host to Six Monodeprotonated Arene Anions

Abstract

Six arene anions in a cationic [K6Mg6N12]6+ ring (see picture, arene=benzene) are reported in the mixed-metal macrocyclic amide of 24 (!) ring atoms. The macrocycle is produced through a very effective synthesis, in which the anions are selectively monodeprotonated.
