摘要
环戊二烯基希土氯化物是一类合成希土有机配合物的重要前身。尽管在1980年前没能成功地合成含轻希土元素的这类配合物,但目前已发现,采用具有较大体积的取代环戊二烯做配体,如C_5Me_5H,C_5H_3〔Si(CH_3)_3〕_2H,C_5Me_4C_3H_7H和桥联的配体(C_5H_4)_2(CH_2)_3H_2都可得到相应的取代环戊二烯基轻希土氯化物。控制LnCl_3和CpNa的反应摩尔比也可以成功地得到这类轻希土的环戊二烯基氯化物。
The title complex was prepared in good yield by the reaction of NdCl3·2LiCl with one equivalent of CH3C5H4Na in THF at room temperature. The complex was characterized by IR spectra, elemental analyses and X-ray single crystal diffraction. The complex crystallizes in the monoclinic space group P21 / n with α= 12.130(5), b= 17.343(5), c= 17.016(5)A, β=108.54(3)°,V=3393.87A3, Z = 4 and Dc= 1.45gcm-3. The structure was solved by Patterson and Fourier techniques and refined by least-squares method to R = 0.0505 for 2004 observed reflections.
