Abstract

A series of potentially dinucleating [2+2] macrocyclic ligands with two SNS metal-binding domains separated by a variable polymethylene chain have been prepared. Two examples of these ligands have been structurally characterised. These ligands form polymeric adducts with [Rh₂(O₂CCMe₃)₄] in which the ligands are thought to act as exocyclic S-donors to the axial sites of the dinuclear complex. In contrast, reaction with [(CO)₂Rh(μ-Cl)₂Rh(CO)₂] resulted in the formation of dinuclear complexes in which two Rh(CO) units are bound to each macrocyclic ligand.
