氨氣是工業界及自然界極為重要的化合物，氮氣在地球上含量豐富，
且容易取得，利用它與適當的金屬催化劑反應產生氨氣是較具有經濟效益的方法。目前實驗室已經發展出一系列含氮磷的配基，分別為二芽基的N^P 配基與三芽基的N^P^N 配基，在N^P 配基方面：我們成功的與過渡金屬錳、鐵、鈷反應並純化得一系列的錯合物，並且利用X-ray 單晶繞射儀鑑定其結構。在N^P^N 配基方面：N^P^N 配基具有三種與金屬鍵結的模式，分別為中性的N^P^N 配基、帶負一價N^P^N 配基、帶負二價N^P^N配基，也利用了X-ray 單晶繞射儀成功的鑑定。此外，我們也將帶負一價N^P^N 配基與氯亞化鐵反應，並且順利純化出鐵錯合物。

Ammonia plays an important role in industry and nature.
Nitrogen is abundant and gained easily. It is more ommercial
benefit that using the nitrogen to mix with suitable metal-catalyst to create ammonia. We have developed a series of ligands that are hybridized by N and P. One of them is the N^P ligand that is bidentate and the other is the N^P^N ligand that is tridentate Presently, we have successfully prepared complexes M(N^P)(μ-Cl)2(Li)(THF)(Et2O) ( M = Mn、Fe、Co ) in good yields by treatment of one equivalent
of lithium salt of N^P ligand with a MCl2 .The complexes are
confirmed by X-ray single crystal diffraction. There are three binding modes of the N^P^N ligand binds to metal. It includes N^P^N、[N^P^N]Li、[N^P^N]Li2 .They are also identified by X-ray single crystal diffraction. Beside, we treat one equivalent of the [N^P^N]Li ligand with a FeCl2 and isolate iron(Ⅱ) complex successfully.
