The authors have prepared a series of monometallic and homo- and heterodimetallic and -trimetallic complexes of Ru and Os with the ligand tetra-2-pyridyl-1,4-pyrazine (tppz) along with mixed-ligand complexes with terpyridine and vinylterpyridine. Their electrochemical and spectroscopic properties were studied and are reported herein. All monometallic complexes were found to be luminescent at both room and liquid-nitrogen temperatures. Electrochemical measurements of dimetallic and trimetallic complexes point to metal-metal interactions as well as to modulations in the [pi]-accepting character of the bridging pyrazine ligand induced by the metal centers. 17 refs., 14 figs., 4 tabs.
