近年來含氮配位基的鉗合劑受到化學家的研究與討論，尤其是含P, N-配位基的過渡金屬錯合物，而P, N-配位基有個特點就是將軟電子予體和硬的電子予體相互結合，這裡所要討論的是PNP含、氮三配位基(2,6-bis[(diphenylphosphino)methyl]pyridine ─ 含有一個含氮砒啶環和兩個含磷的-CH2PPh2配位。我們使用不同的起始物來合成含PNP配位基的金屬錯合物，由錯合物的X-ray單晶結構分析可確認含PNP鉗合劑錯合物的結構。在錯合物活性的測試上，包含對酸鹼的反應研究及氫醯反應的研究。

Recently the studies of polydentates containing nitrogen and phosphorus donor atoms have received much attention, especially P, N-bidentate ligands. One particular aspect of such P, N-bidentate ligand is the combination of a hard and a soft donor atom site. A PNP-tridentate ligand (2,6-bis[(diphenylphosphino)methyl]pyridine) with one pyridyl ring and two —CH2PPh2 was synthesized. Reactions of M(PPh3)4 (Pd, Pt, Ni) with PNP form new complexes [M(PNP)(R)](BPh4) (R= -C3H3, -CH3, -C6H5, -CH2C6H5). From the X-ray crystal analysis, the structure of complexes is confirmed. The reactivity of hydroformylation is poor.
