    Abstract: 本論文主要是以離子熱法合成一系列金屬草酸磷酸鹽化合物;其中化合物1、2是以鐵為中心金屬所合成的草酸磷酸鹽化合物,化合物3是以鋁為中心金屬,化合物4則是以鎳為中心金屬所合成的化合物。此四個化合物都含有銫離子存在於孔洞之中,扮演平衡電荷的角色。 茲將這四個化合物整理如下: I. 三維鐵草酸-磷酸化合物 Cs2Fe(C2O4)0.5(HPO4)2 (1) 二維鐵草酸-磷酸化合物 CsFe(C2O4)0.5(H2PO4)(HPO4) (2) II. 二維鋁草酸-磷酸化合物 CsAl(C2O4)0.5(H2PO4)(HPO4) (3) III. 一維鎳草酸-磷酸化合物 CsNi0.5(C2O4)0.5(H2PO4) (4) 以上各化合物均可得到晶體,利用單晶X-光繞射分析鑑定其結構;由粉末X-光繞射分析證實產物的純度;利用元素分析確定結構中C、N、H等元素的比例;熱重分析探討化合物的熱性質;傅立葉紅外線吸收光譜儀(FT-IR)分析不同官能基的特定吸收峰,來鑑定化合物中的有機分子;超導量子干涉磁量儀(SQUID)磁性分析化合物的磁性行為。 Four new Metal phosphatooxalates, Cs2Fe(C2O4)0.5(HPO4)2 (1)、 CsFe(C2O4)0.5 (H2PO4)(HPO4) (2)、CsAl(C2O4)0.5(H2PO4)(HPO4) (3)、CsNi0.5(C2O4)0.5(H2PO4) (4) have been synthesized by Ionic Liquids as solvent and characterized by single-crystal X-ray diffraction. The structure of 1 comprises FeO6 octahedra and HPO42- tetrahedra forming 12- membered ring channels, in which the charge compensating Cs+ cations are present within the channels and connected via bisbidentate oxalate anions to form a 3D framework. The structure of 2 consists of FeO6 octahedra connected by H2PO4- tetrahedra, HPO42- tetrahedra and bisbidentate oxalate anions to form anionic sheets with the Cs+ cations between the sheets. The structure of 3 have the similar layer structure with compound 2. The structure of 4 consists of NiO6 octahedra connected by bisbidentate oxalate anions to form infinite chain.
