    Abstract: [Ru(NH3)5L]2+ ( L=?啶(py),異菸鹼醯胺(isn),4,4’-聯?啶(4,4’-bpy),4-胺基?啶(4-ampy))和[Fe(CN)54-ampy]3-錯合物與[Co(tpy)2]3+的氧化還原反應屬於外圈電子轉移機構,在μ = 0.1M LiCl,pH = 5 ~ 8及T = 25 ℃,反應速率常數分別為1.49 ×103M-1s-1 (py)、2.43 ×102M-1s-1(isn)、3.48 ×103M-1s-1(4,4’-bpy)、8.38 ×104M-1s-1 (4-ampy)及1.97 ×104M-1s-1([Fe(CN)5(4-ampy)]3-),動力學結果符合Marcus理論值。
    Kinetic studies of the oxidations of [Ru(NH3)5L]2+(L=pyridine(py), isonicotinamide(isn), 4,4’-bipyridine(4,4’-bpy), 4-aminopyridine(4-ampy) and [Fe(CN)54-ampy]3- complexes by [Co(tpy)2]3+(tpy = 2,2’:6’,2”-terpyridine) have been carried out at 25℃, pH=5~8, and μ= 0.1M LiCl. The corresponding rate constants are 1.49×103M-1s-1(py), 2.43×102M-1s-1(isn), 3.48×103M-1s-1(4,4’-bpy), 8.38×104 M-1s-1(4-ampy) and 1.97×104M-1s-1([Fe(CN)54-ampy]3-). The kinetic results of our system agree well with the values predicted by Marcus theory.
