(Bpy)2Ru(\textgreek{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 \textgreek{p}*1 and \textgreek{p}*2 are stabilized by effects coming from both metal fragments. Combinations of metal fragments with different \textgreek{p} donor/\textgreek{s} acceptor characteristics give rise to variable charge transfer energies for major transitions d(Ru) $\rightarrow$ \textgreek{p}*1, d(M) $\rightarrow$ \textgreek{p}*1, d(Ru) $\rightarrow$ \textgreek{p}*2; the appearance of spectra is further detd. by different widths and intensities of individual bands and by solvent dependence.
