Abstract: In the title monomeric rare earth complex, [LiNd(C₁₉H₄₀N₃Si₂)₂Cl₂(C₄H₈O)₂], the [(Me₃Si)₂NC(NCy)₂]₂Nd⁺ (Me is methyl, Cy is cyclohexyl) and Li(THF)₂⁺ units (THF is tetrahydrofuran) are connected by two bridging Cl atoms. The Nd³⁺ ion is coordinated by two guanidinate ligands and two Cl atoms, forming a distorted chelating octahedral geometry. The Li⁺ ion is four-coordinated by two Cl atoms and two O atoms from THF molecules in a distorted tetrahedral geometry.
