(Bpy)2Ru(m-bpym)MLn (MLn = Cu(PPh3)2, Mo(CO)4, Re(CO)3Cl) were studied by cyclic voltammetry, absorption spectroscopy, and by ESR of their singly reduced forms. Comparison with the homodinuclear analogs reveals that the metal-centered occupied d orbitals show relatively little change on coordination of a second metal (weak interaction) whereas the bpym-centered lowest unoccupied MOs p*1 and p*2 are stabilized by effects coming from both metal fragments. Combinations of metal fragments with different p donor/s acceptor characteristics give rise to variable charge transfer energies for major transitions d(Ru) $\rightarrow$ p*1, d(M) $\rightarrow$ p*1, d(Ru) $\rightarrow$ p*2; the appearance of spectra is further detd. by different widths and intensities of individual bands and by solvent dependence. on SciFinder(R)
