Generation of a zinc and rhodium containing metallomacrocycle by rearrangement of a six-coordinate precursor complex

Two pentadentate N 3 ,P 2 ligands coordinate zinc( ii ) by their N 3 pocket. Four free phosphine donors allow the coordination of four AuCl moieties leading to a pentanuclear ZnAu 4 complex. In contrast, the attempt to use the phosphines for chelating coordination of two Rh(CO)Cl units results in a well-organized rearrangement that ends up with the formation of a metallomacrocycle in high yields. Two pentadentate N 3 ,P 2 ligands coordinate zinc( ii ) by their N 3 pocket.
