A Sandwich-Shaped Hexanuclear Silver Complex with a Giant Cavity Constructed from a Macrocycle with Inward Chelating Units

The formation of a macrocyclic hexanuclear silver complex with a giant cavity (diameter similar to 16.5 angstrom) is reported. Six silver centers are sandwiched by two molecules of a macrocyclic ligand possessing six pap (2-[(pyridin-2-ylmethylene)amino]phenol) chelating units, and the metals are arranged on the wall of the internal cavity. Various analytical techniques revealed that each pap binds to the silver as an NN bidentate ligand.
