15 - 002Synthesis, Characterization, and Photophysical Properties of aSeries of Supramolecular Mixed-Valence Compounds. — Tendifferent cyano-bridged trinuclear mixed-valence compounds of general formula[(NH3)5M–NC–FeII (CN)4–CN–M1(NH3)5] n+ (M, M1: RuIII , OsIII , CrIII ,PtIV ; n = 2, 3, or 4) are prepared by mixing aqueous solutions of K[(NH3)5M–NC–FeII(CN)5] and [M(NH3)5(OSO2CF3)] (OSO2CF3)2 (∆, 15–30 min). Thesamples are characterized by UV/VIS, IR, and ICP spectroscopy, as well asby differential pulse or cyclic voltammetry. The electronic coupling withinthese complexes is discussed. — (PFENNIG, BRIAN W.; FRITCHMAN,VIRGINIA A.; HAYMAN, KATIE A.; Inorg.
