  摘要：

  Reactions of anhydrous YbCl3 and NdCl3 with dilithium N,N'-di(trimethylsilyl)-p-benzenediamide in THF in 1:1 molar ratio afforded a cyclic binuclear complex of Yb, [{mu(2)-p-(Me3SiN)(2)C6H4}YbCl(THF)(2)](2) (1), and a cyclic tetranuclear complex of Nd, [{mu(2)-p-(Me3SiN)(2)C6H4}Nd(mu(2)-Cl)(THF)](4)(.) 2PhMe (2), respectively, in good isolated yields. 1 is a hexagon consisting of two Yb atoms and four nitrogen atoms from two bridged diamides, while 2 is a cage-like macrocycle formed via assembly by weak bonding of Nd-C (aromatic carbon), in which each Nd atom is coordinated to two nitrogen atoms from two linked diamide ligands, respectively, two bridged chlorine atoms, and one oxygen atom of THF, additionally, interacting with the three aromatic carbons from two phenyl groups, respectively.
