本論文主要為合成十一氮配基H4bpyanyapy,全名為2,6-bis(2-α- pyridylamino-1,8-naphthyridyl-7-amino)pyridine,並用此配基與NiCl2以實驗室所開發的萘燒技術合成直線形的金屬串錯合物。 我們成功的得到了十一氮配基,並且也利用奈燒的技術合成出了四核以及十一核鎳金屬串錯合物。但是因為養晶上的困難,並未能得到十一核鎳金屬串錯合物的X-ray繞射資料。 四核鎳金屬串錯合物可以有多種去質子化的結構且在空氣下都還算穩定。不同質子化數量的四核鎳金屬串有不同的溶解度。在單晶繞射的資料,我們還可細微的分析質子化以及去質子化在配基上所發生的鍵長變化。 四核鎳金屬串錯合物還可以進一步與甲基碘 (CH3I) 反應,接上一個甲基。但是和TsCl的反應性不佳,可能是立體阻礙的因素,也可能是去質子化後的四核鎳金屬串親核性並不佳。 由磁性的測量得知四核鎳金屬串錯合物的反鐵磁性偶合的強度是介於三核與五核鎳金屬串錯合物之間,跟實驗室一系列金屬串錯合物的磁性趨勢是吻合的。以反鐵磁偶合的能量-J和R-3作圖也能呈線性關係,符合我們的預測。
This thesis is presented to investigation of nickel string complexes which are composed of the bis(2-α-pyridylamino-1,8- naphthyridyl-7-amino)pyridine ligand. We have successfully synthesized clipped and linear forms of nickel string complexes, but we failed to grow the single crystal of the undeca-nuclear metal linear metal complex. The clip type tetra-nuclear complexes can be deprotonated, and each protonated form exhibit different solubility. We can observe the small changes on the bond length of the ligand of these complexes, by structural analysis. The tetranuclear metal string complexes may further react with methyl iodide, but cannot react with tosyl chloride. It is possibly due to the steric hinderence and poor necleophilicity. The anti-ferromagnetic coupling strength of tetra-nuclear nickel metal string complex lay between tri-nuclear and penta-nuclear complexes. It is in a good agreement with the trend of a series of metal string complexes in our lab.
