| Summary: | 碩士 === 國立中央大學 === 化學研究所 === 95 === Four organic-inorganic hybrid compounds, (H4A)[U2F6(C2O4)3]‧4H2O [A = tris(2-aminoethyl)amine (A1) and 1,4-bis-(3-aminopropyl)piperazine (A2)] and M(H2O)(C2O4)0.5(HPO3)‧H2O [M = Er (B1) and Yb (B2)], have been synthesized by hydrothermal methods and structurally characterized by single-crystal X-ray diffraction, thermogravimetric analysis, and magnetic analysis.
Both A1 and A2 consist of anionic layers, [U2F6(C2O4)3]4-, separated by organic ammonium cations and lattice water molecules. The UF3O6 polyhedra are connected by oxalate ligands with different types within the layers. A1 and A2 are the first example of organically-templated uranium fluorooxalates.
Both B1 and B2 comprise LnO8 decahedra and HPO3 tetrahedra forming 2-D layers which connected via bisbidentate oxalate anions to form a 3-D framework, and delimit 8-membered ring channels alone a axis. B1 and B2 are the first example of lanthanide oxalatophosphite.
