本工作合成了轻稀土氯化物与2,3,11,12-四苯基-1,4,7,10,13,16-六氧-2,11-十八环二烯不饱和冠醚所形成的三种新的轻稀土配合物, 我们着重对这些配合物进行了X射线光电子能谱研究, 得到了组成原子芯能级电子(Ln3d5/2, O 1s, C 1s, Cl 2p)的结合能变化信息。

MCl3 and L (M = Ce, Pr, Sm; L = 2,3,11,12-tetraphenyl-1,4,7,10,13,16-hexaoxa-2,11-cyclooctadecadiene ) produced complexes of 1:1 stoichiometry. The core (M3d5/2), O1s, C1s, Cl2p) of the reactant salt and its complexes was studied by XPS. Satellite phenomena were observed for the M electron signals in all cases. These are attributed Cl3p to M charge transfer excitations. The satellites of Ce are due to transition energy >0; those of Pr and Sm are due to transition energies <0. The former belong to shake-up processes and the latter to shake-down processes.
