摘要: 将加热活化的AlCl3与三氯化稀土在苯溶液中反应,合成了2个新的轻稀土中性芳烃配合物RE(C6H6)(AlCl4)3C6H6(RE=La或Nd)。并用元素分析和红外光谱对其进行了表征。测定了含Nd配合物的晶体结构。对2个配合物结构的比较表明,中心金属离子对配合物的结构无明显影响,其键参数的差别主要来自“镧系收缩”。

Abstract: AlCl3 which was activated by heating with aluminum powder reacts with RECl3 in benzene solution giving two new neutral arene complexes, RE(C6H6)(AlCl4)3C6H6(RE = La, Nd).The complexes were characterized by elemental analysis and IR spectra measurement. The molecular structure of necdium containing complex has been determined. It's isomorphous and isostructural with Sm(C6H6)(AlCl4)3C6H6. The Nd-C and Nd-Cl bond lengths are respectively longer than Sm-C and Sm-Cl bond lengths in corresponding Sm-containingcomplex

Key words: light lanthanoids, neutral arene complex, synthesis, structure
