- 中文摘要: The preparation and physical properties of the new heterotrinuclear acetates, [ Ru/sub 2/Co(.mu./sub 3/-O)(.mu.-CH/sub 3/CO/sub 2/)/sub 6/(Py)/sub 3/] (Ru/sub 2/Co(II)) and [ Ru/sub 2/Co(.mu./sub 3/-O)(.mu.-CH/sub 3/CO/sub 2/)/sub 6/(Py)/sub 3/] I/ sub 3/(Ru/sub 2/Co(III), Py=pyridine), are reported. Three reversible one-electron-redox waves are observed at 1.19, 0.40, and -1.24V vs Ag/Ag/sup +/ electrode for Ru/sub 2/Co(II) in CH/sub 2/Cl/sub 2/. The complexes of Ru/sub 2/Co(II) and Ru/sub 2/ Co(III) show an intense visible absorption at 570 (.epsilon. 5950M/sup -1/cm/sup -1/) and 551nm (.epsilon. 7240M/sup -1/cm/sup -1/), respectively. The magnetic susceptibilities of both complexes were also measured from 4.2 to 300K. The resulting least-squares fit parameters for Ru/sub 2/Co(II) are J/sub RuCo/=-9cm/sup -1/, J/sub RuRu/=-22cm/sup -1/, g/sub Co/=g/sub Ru/=2.19.
