New Sm(III) -halo-bis(trimethylsilyl)amido complexes [Sm(-X) {N(SiMe 3 ) 2 } 2 (THF)] 2 (X ϭ Cl, Br) were synthesized and their crystal structures were analyzed. These complexes were used as catalysts for the homopolymerization of -caprolactone and ␦-valerolactone and found to initiate ring-opening
