　　在過去有許多對金屬與金屬間，分子內的電子轉移的研究中，常利用改變不同橋基使
電子在傳遞的過程中產生不同程度的影響。而橋基的屬性，通常是影響分子內電子轉移速
率的一項重要因素。
　　在橋基上的選擇，我們選用以Spy作為橋基。由於許多以單硫為橋基化合物，兩金屬
間的電子溝通程度並不好，因此我們加上了一個有良好π電子的py，來加強電子溝通的程
度。還有在本論文中，我們合成了以Spy作為橋基的化合物〔FcSpyRuA5〕(PF6)2(A＝
NH3)來研究電子在鐵與釕之間的溝通程度。在實驗中，我們發現DN對二茂鐵的氧化還原電
位沒有影響，但是對Ru(NH3)5部份的氧化還原電位卻是影響極大，另外IT band的位置也
會受到D.N.的影響，尤其是D.N.最小的MeNO2，剛好把本來被擋住的IT band給拉了出來。

　　In search long-range electronic communication between metal centers through organic matrix, a series of complexes containing Pentaammineruthenium(II) and ferrocene moties were synthesized. The bridging group chosen to link Cp and lead in ruthenium center is Spy. We hope adding pyridine can make the communication between Fc and Ru(NH3)5 moties better.
The heterobinuclear complexes[FcSPyRu(NH3)5](PF6)2 were synthesized and studied in this work.
　　This compound shows two sets of reversible waves in its cyclic voltammogram, the smaller set is from Ru2＋-Ru3＋ and the other is from Fc-Fc＋.
　　We found donor number doesn't affect the potential of Fc-Fc＋ but does affect the potential of Ru2＋-Ru3＋ a lot.
　　In Near-IR specta, DN affects the energy of intervalence band. So we use MeNO2(the DN is smaller solvent) to find the IT band.
