“…The EPR spectra obtained for the series have been compared to those for the structurally analogous monomeric complexes [Cu(phdpa)(dmf ) 2 ](ClO 4 ) 2 14 and [Cu(dpa)(bipy)](ClO 4 ) 2 10 in order to assist in the separation of spectroscopic features of the copper based moieties in the dinuclear copper and trinuclear copper ruthenium complexes. EPR spectra of the di-and trinuclear complexes in frozen MeOH/dmf (3 : 1) and MeOH/ water Redox activity based on the copper ions, ruthenium ion and tpbd ligand is feasible for the trinuclear complexes, potentially bipy-based redox chemistry is also possible.…”
