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

The complex [{(TMS)<sub>2</sub>N}<sub>4</sub>(μ<sub>4</sub>-Cl)Sm<sub>4</sub>(μ-SPh)<sub>4</sub>(μ<sub>3</sub>-Cl)Li(THF)] has been formed by protonolysis of [(Me<sub>3</sub>Si)<sub>2</sub>N]<sub>3</sub>Sm(μ-Cl)Li(THF)<sub>3</sub> with 1 equiv of HSPh, which contains a square array of Sm(III) ions connected by a central μ<sub>4</sub>-Cl ligand. The edges of the square Sm<sub>4</sub> array are bridged by four μ<sub>3</sub>-Cl and four μ-SPh ligands. The four Sm atoms and Li atom are connected by four μ<sub>3</sub>-Cl ligands.
