摘要：
The crystal structure of Li3ThF7 has been refined by Rietveld analysis of neutron powder diffraction data at several temperatures. Li3ThF7 exhibits a phase transition between 295 and 350K, and becomes tetragonal (P4/ncc). Moreover, Li3ThF7 becomes ionic conductor above 500K. Fourier maps revealed that conducting lithium ions move in the a,b plane at the surface of a double layer, and, to a lower extent, between two double layers.
