摘要
为了研究萘基以σ键同稀土金属配位的特点与性质,用α-萘锂与二茂稀土一氯化物反应,合成了六个新型含σ键的萘基二茂稀土有机配合物C10H7LnCp2(Cp=η5-C5H5,Ln=Yb,Ho,Dy,Tb,Gd,Sm)。对配合物进行了元素分析、红外及质谱表征,发现它们在空气中不稳定,轻稀土配合物存在歧化现象。
Six new organolanthanide complexes Cp2LnNp (Ln=Yb,Ho,Dy, Tb,Gd, Sm) were synthesized by the reaction of α-NpLi and Cp2LnCl in THF at room temperature These complexes were characterized by elemental analysis,IR and mass-spectrometry
