Abstract
The bridged ruthenium cluster-polypyridine dimer [Ru3O (CH3COO)(6)(py)(2)(t mbpy)Ru(bpy)(2)(Cl)](PF6)(2) (py = pyridine, bpy = 2,2'-bipyridine and tmbp y = 4,4'-trimethylenedipyridine) has been synthesized and structurally char acterized based on H-1 and C-13 NMR spectroscopy. This species exhibits a c omplex 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 H -1 and C-13 NMR spectra.
