摘要：

The LnOCl (Ln = Y, Lu) compounds have been successfully co-intercalated by Li and THF molecules. Infrared spectroscopy and atomic absorption spectroscopy agree with the formulation Li-x(THF)(y)LnOCl (Ln = Y, Lu; x ranging from 0.07 to 0.37). Characterizations by means of X-ray powder diffraction shows that these products are isotypic with the superconducting Li-x(THF)(y)MNCl (M = Zr, Hf) compounds (T-c up to 25.5 K). Band structure calculations performed for YOCl and ZrNCl indicate that the bottom of the conduction band is similar for both compounds. However, from magnetic susceptibility measurements none of the Li-x(THF)(y)LnOCl (Ln = Y, Lu) compounds were found to be superconducting down to 2 K.
