摘要

中文摘要

本論文主要探討含N,N¢-di(2-pyridyl)oxamide 和N-pyridin-2-yl-oxalamic acid配位基與一價銀金屬化合物的化學。
使用一價銀金屬化合物AgX ( X = BF4-, ClO4-, PF6- 和NO3-) 與配位基N,N'-di(2-pyridyl)oxamide (H2DpyO) 在EtOH / H2O下反應，得到化合物　{[Ag2(H2DpyO)2(pyOa)](BF4)} V , 1；[Ag2(H2DpyO)2(pyOa)](ClO4)} V , 2 ；{[Ag2(H2DpyO)2(pyOa)](PF6)} V , 3及化合物{[Ag2(H2DpyO)2(pyOa) (NO3)]} V , 4 ，其中pyOa為N-(2-
吡啶) 乙二醯胺酸根。
化合物1~4中每個銀原子均與H2DpyO及pyOa兩種配位基鍵結。配位基H2DpyO藉由吡啶環上的氮以橋接的方式連結兩個的銀原子，而配位基pyOa則以羧酸基上兩個氧原子及吡啶環上的氮原子與兩個銀原子鍵結。
參與反應的一價銀金屬起始物AgBF4、AgClO4、AgPF6中的陰離子，在化合物1~3中並未與銀原子進行鍵結，但藉由(Ag…O , Ag…F)作用力與(Cpy–H…F-B , Cpy–H…O-Cl , Cpy–H…F-P)等氫鍵連結，進而穩固晶體之整體結構；而化合物4的配位結構中，陰離子NO3-則利用一個氧原子與銀原子間進行配位，並以Cpy–H…O–N氫鍵作用力穩固晶體之整體結構。化合物1~4之Ag原子皆有五配位和四配位兩種鍵結模式，並以交錯且規則的方式排列，並以此形成新型三維網狀的超分子結構化合物。

ABSTRACT

This thesis discusses the supramolecular chemistry of silver (Ⅰ) complexes containing polydentate nitrogeneous ligands. A series of silver (Ⅰ) complexes of the types {[Ag2(H2DpyO)2(pyOa)](BF4)} V, 1 , {[Ag2(H2DpyO)2(pyOa)](ClO4)} V, 2 , {[Ag2(H2DpyO)2(pyOa)](PF6)} V, 3 and {[Ag2(H2DpyO)2(pyOa)(NO3)]} V, 4 , have been prepared by reaction of AgX ( X = BF4-, ClO4-, PF6-, NO3-) with H2DpyO ( H2DpyO = N,N'-di(2-pyridyl)oxamide ) in EtOH / H2O , where pyOa is anion of N-pyridin-2-yl-oxalamic acid .
The H2DpyO ligand in 1~4 are coordinated to the silver (Ⅰ) centers through two terminal pyridine nitrogen atoms, while the pyOa ligands are coordinated to silver (Ⅰ) centers through two oxygen atoms and the pyridine nitrogen atoms , forming ladder -type structures .
The anions , BF4- , ClO4- and PF6- are not coordinated to the silver (Ⅰ) atoms in complexes 1~3. The ladders are interlinked to each other through a series of Ag…O , Ag…F interactions and Cpy-H…F-B , Cpy-H…O-Cl , Cpy-H…F-P hydrogen bondings , while the molecules are interlinked to each other through Cpy-H…O-N hydrogen bondings in complex 4.
