摘　　要：The reactions of dilithium salt of trans-1,2-bis（trimethylsilylamino）cyclohexane with anhydrous lanthanide trichlorides LnCl3 （Ln = Yb, Nd） in THF afforded the dianionic binuclear tricycles of lanthanide chlorides {Li（THF）3[LnCl（μ2-trans-1,2-（NSiMe3）2C6H10）（μ2-Cl）]}2·2THF （Ln=Yb 1, Nd 2） in moderate yields. Both of the bridged complexes were characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Crystal structural analysis shows that the two complexes are the analogues which have a tricyclic framework built by two bridged lanthanide metals, four nitrogens and four carbons from two diamide ligands. Each lanthanide metal coordinates to three nitrogen atoms and two chlorines to form a distorted trigonal bipyramid and connects with a lithium by a bridging chlorine.The reactions of dilithium salt of trans-1,2-bis（trimethylsilylamino）cyclohexane with anhydrous lanthanide trichlorides LnCl3 （Ln = Yb, Nd） in THF afforded the dianionic binuclear tricycles of lanthanide chlorides {Li（THF）3[LnCl（μ2-trans-1,2-（NSiMe3）2C6H10）（μ2-Cl）]}2·2THF （Ln=Yb 1, Nd 2） in moderate yields.
