Tetrametallic rectangular box complexes assembled from heteroligated macrocycles

摘要

The reaction of a heteroligated Rh(I)bimetallic macrocycle with rigid ditopic ligands (1,4-dicyanobenzene,4-4'-dicyanobiphenyl,or dipyridyl terminated salen ligand 5)results in the formation of tetrametallic rectangular box complexes.Over the past decade,supramolecular chemistry has evolved beyond simple macrocycles to involve more complex two-and three-dimensional architectures such as cylinders,squares,and prisms.
