A procedure for the synthesis of three‐dimensional hexakisimidazolium cage compounds has been developed. The reaction of the trigonal trisimidazolium salts H3L(PF6)3, decorated with three N‐olefinic pendants, and silver oxide yielded trinuclear trisilver(I) hexacarbene molecular cylinders of the type [Ag3L2]3+ with the olefinic pendants from the two different tricarbene ligands arranged in three pairs

present work verified the potential application of the metal–carbene template approach (MCTA) in the preparation of novel flexible polyimidazolium cages by photochemical [2+2] cycloaddition reactions and may provide a new method for the preparation of flexible pure organic cages with incorporation of a variety of functional sites.
