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.
