Metallosupramolecular 3D assembly of dimetallic Zn 4 [RuL 2 ] 2 and trimetallic Fe 2 Zn 2 [RuL 2 ] 2

A novel metallo-organic ligand [RuL ] with four uncomplexed coordination sites was created, and upon treatment with Zn generated a dimetallic 3D metallosupramolecule in nearly quantitative yield. This self-assembly process gave stable intermediates, opening the pathway to the first 3D metallo-assembly possessing two Ru , two Fe , and two Zn ions precisely located in the different edges. This strategy opens the door to novel designer 3D polymetallic constructs capable of diverse applications.
