Only the central metal atom of the homotrinuclear complex [LZn 3 ] 2+ , prepared by cooperative complexation between a linear ligand and Zn(OAc) 2 , is replaced with a Ln 3+ ion by selective and quantitative transmetalation to give a helical heterotrinuclear complex [LZn 2 Ln] 3+ (see scheme). Ln=lanthanide.
