摘　　要：在N_2气气氛保护下,以KBH_4作为还原剂,通过C_(60)和Ru(OCOCF_3)_2(CO)(PPh_3)_2反应合成出C_(60)Ru(OCOCF_3)(CO)(PPh_3),利用元素分析、红外光谱、紫外可见光谱、核磁共振、光电子能谱等手段对产物进行了表征。结果表明,配合物中^-OCOCF_3、CO、PPh_3各占据中心金属的1个配位位置,C_(60)以σ-π方式占据其余2个位置。配合物的氧化还原研究结果表明,配合物的还原电位比纯C_(60)的还原电位负。Fullerene complex C_(60) Ru(OCOCF_3)(CO)(PPh_3) was perpared by reduction-substitution reactionof C_(60) with Ru (OCOCF_3)_2(CO)(PPh_3)_2 under nitrogen atmosphere and refluxing, and the complex was characterized by elemental analysis, FT-IR, UV-vis, ^(13)C NMR and XPS. The results showed that in complex each moiety of PPh_3, OCOCF_3, and CO takes one coordination site from the central metal, and C_(60) takes the two remaining sites in σ-π back-bonding. The redox experiments of the complex indicated the reduction potential of the complex was more negative than that of the pure C_(60).
