Cerium(III) and neodymium(III) amides derived from a chelating 2-pyridyl amido ligand
Homoleptic Ce(III) and Nd(III) triamides [LnL(3)] [Ln = Ce (1) or Nd (2)] and the heterobimetallic amide-alkoxide derivatives [LnL(2)(mu-OBut)(2)(tmeda)] [Ln = Ce, M = Na (3); Ln = Nd, M = Na (4); Ln = Nd, M = K (5)] supported by the bulky [N((SiBuMe2)-Me-t)(2-C5H3N-6-Me)](-) ligand (L-) have been successfully synthesized and characterized. Complexes 1-3 and 5 show a high activity toward the ring-opening polymerization of epsilon-caprolactone.
