摘要: Rossmanith[1]报导,无水NdCl3和萘锂在THF溶液中可生成NdCl2·2THF。我们在研究这一类型化合物时考察了NdCl3·2THF和CpNa(Cp为环戊二烯)在THF中的反应,分离出一种氢化物——[Na·6THF][Cp3Nd(μ-H)NdCp3]·2THF。

Abstract: The title complex crystallizes in space group P-1 with a=16.834(6)Å, b=16.988(7)Å, c=10.696(4)Å,α=91.99°(3), β=96.68°(3),γ=91.42°(3)and Z=2. The crystal is air and X-ray sensitive. Diffraction data had to be collected at low te-mperature (about -110℃) on four circle diffractometer. Least squares refinement led to a final R=0.074. The structure analysis proved that the complex is polymorphic at different temperature.
