| Summary: | 碩士 === 國立中央大學 === 化學研究所 === 94 === 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.
