Summary: | 碩士 === 國立中央大學 === 化學研究所 === 93 === Recently, Uranium chemistry becomes greatly inviting, owing the high coordination numbers and variety of coordination geometries could be expected to synthesize new, complex framework architectures in the presence of organic species, and the demonstrated applications in fabrication of devices with optical, magnetic, and catalytic properties.
We have synthesized some interesting compounds under hydrothermal conditions.
[N(CH2CH2NH3)3][U3O2F13]·2H2O (U-1) 2D layer
[N(CH2CH2NH3)3] [U3F15] (U-2) 2D layer
[H4APPIP][U4F20] (U-3) 2D layer
[H3DETA][U2F11] (U-4) 2D layer
[H4TETA][U2F12] (U-5) 1D chain
These compounds have been characterized by single-crystal X-ray diffraction, thermogravimetric analysis, and magnetic susceptibility measurements.The variable-temperature magnetic susceptibility of these compounds are consistent with antiferromagnetic interactions between U(IV) centers.
