Photochemical or Thermal Chelate Exchange in the Ruthenium Coordination Sphere of Complexes of the Ru(phen)<sub>2</sub>L Family (L = Diimine or Dinitrile Ligands)
was obtained. By heating Ru(phen)(2)L'(2+) with a bipy derivative in refluxing ethylene glycol, quantitative formation of the starting complex [Ru(phen)(2)L(2+)] was carried out. The present series of compounds presents properties that could be profitably used in the design and construction of multicomponent systems acting as photochemicallydrivenmolecularmachines.

geometry was observed whereas for [Cu(dCN3)2][PF6], a polymeric assembly was formed. A further extension of this work involved the syntheses of two threaded species bearing the M30 macrocycle, Cu metal and a dCNn ligand. The formation of the desired complexes was confirmed by means of mass spectrometry as well as 1-D and 2-D 1H NMR spectroscopy. Finally, the cyclic voltammograms of all 4 new species
