Two series of new lanthanide amido complexes supported by bis(indolyl) ligands with amino-coordinate-lithium as a bridge were synthesized and characterized. The interactions of [(Me3Si)2N]3LnIII(μ-Cl)Li(THF)3 with 2 equiv of 3-(CyNHCH2)C8H5NH in toluene produced the amino-coordinate-lithium bridged bis(indolyl) lanthanide amides [μ-[η1:η1:η1:η1-3-(CyNHCH2)Ind]2Li}Ln[N(SiMe3)2]2] (Cy = cyclohexyl,
