摘要：

The synthesis, spectra and electrochemistry of [Ru(bipy)2(picOH)]+ and {mu-picO-[Ru(bipy)2]2]2+ (bipy = 2,2'-bipyridine and picOH = 3-hydroxypicolinate ion) are described. The spectroscopic properties in the visible region are dominated by the intense Ru --> bipy charge-transfer transitions. In the binuclear complex, the two [Ru(bipy)2L]2+ moieties are nonequivalent, exhibiting E1/2 = 0.69 and 1.20 V versus s.h.e. The partially oxidized species exhibits a weak intervalence transfer band at 1085 nm, and is consistent with a Robin-Day class II mixed valence complex.
