摘　　要：A bimetallic oxalamidino complex of neodymium [（Cp＇＇）2Nd（NR）2C-C（NR＇）2Nd（Cp＇＇）2][Cp＇＇= η5-C5H3-1,3-（SiMe3）2, R=C6H11]（2） was obtained via reaction between Ndl2 and carbodiimide[RN：C：NR] （R=C6H11）（molar ratio 1：1） in tetrahydrofuran（THF） solution, followed by the addition of [KCp＇＇（THF）]（1）（molar ratio 1：2） at a low temperature through a reductive-coupling reaction with carbodiimide. The structure of the intermediate product was confirmed by means of elemental analysis, ^1H NMR and ^13C NMR. Characterization of the product by single crystal X-ray diffraction confirmed the diamidinate type of structure.A bimetallic oxalamidino complex of neodymium [（Cp＇＇）2Nd（NR）2C-C（NR＇）2Nd（Cp＇＇）2][Cp＇＇= η5-C5H3-1,3-（SiMe3）2, R=C6H11]（2） was obtained via reaction between Ndl2 and carbodiimide[RN：C：NR] （R=C6H11）（molar ratio 1：1） in tetrahydrofuran（THF） solution, followed by the addition of [KCp＇＇（THF）]（1）（molar ratio 1：2） at a low temperature through a reductive-coupling reaction with carbodiimide.
