TOTAL ASSIGNMENT OF 1H AND 13C NMR SPECTRA OF A BRIDGED TRIRUTHENIUM CLUSTER-POLYPYRIDINE DIMER BASED ON 2D (COSY,HMQC, AND HMBC) TECHNIQUES |

Abstract: | The bridged ruthenium cluster-polypyridine dimer [Ru3O(CH3COO)6(py)2(tmbpy)Ru(bpy)2(Cl)](PF6)2 (py = pyridine, = 2, 2′-bipyridine and tmbpy = 4, 4′-trimethylenedipyridine) has been synthesized and structurally characterized based on 1H and 13C NMR spectroscopy. This species exhibits a complex pattern of NMR signals due to the presence of a paramagnetic [Ru3O] core and seven non-equivalent aromatic rings. 2D NMR (COSY, HMQC and HMBC) correlation techniques have been required for the total assignment of the 1H and 13C NMR spectra. |
