Construction of Polymeric and Oligomeric Lanthanide(III) Thiolates from Preformed Complexes [(TMS)2N]3Ln(μ-Cl)Li(THF)3 (Ln = Pr, Nd, Sm; (TMS)2N = Bis(trimethylsilyl)amide)

The complex [{(TMS)2N}44-Cl)Sm4(μ-SPh)43-Cl)Li(THF)] has been formed by protonolysis of [(Me3Si)2N]3Sm(μ-Cl)Li(THF)3 with 1 equiv of HSPh, which contains a square array of Sm(III) ions connected by a central μ4-Cl ligand. The edges of the square Sm4 array are bridged by four μ3-Cl and four μ-SPh ligands. The four Sm atoms and Li atom are connected by four μ3-Cl ligands.
