Reactions of [(Me3Si)2N]3Ln(μ-Cl) Li(thf)3 (1: Ln = Pr; 2: Ln = Sm) with an equimolar amount of tBuSH or EtSH gave rise to four amidolanthanide alkylthiolate complexes [{(Me 3Si)2-N}2Ln(μ-StBu)]2 (3: Ln = Pr; 4: Ln = Sm) and [Li(thf)4][{(Me3Si) 2-N}4Ln4(μ4-SEt)(μ-SEt) 8] (5: Ln = Pr; 6: Ln = Sm). Compounds 3-6 were characterized by elemental analysis, IR and 1H NMR spectroscopy and single-crystal X-ray diffraction, and their catalytic properties were also investigated. Compounds 3 and 4 are thiolate-bridged dimers in which each Ln atom adopts a distorted tetrahedral coordination. Compounds 5 and 6 contain a Ln4 square plane, which is capped by a μ4-SEt- ligand. The edges of the square are bridged by four pairs of SEt- ligands on both sides of the Ln4 plane. Each Ln atom has a distorted octahedral geometry. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
