The First Isolation and Structural Analysis of Chalcogenocarboxylato Samarium Complexes, [(RCOS)<sub>3</sub>Sm(thf)<sub>2</sub>] and [Na(thf)<sub>4</sub>][Sm(RCSS)<sub>4</sub>]; The Alkali Metal Salt-Like Reaction and the Insertion Reaction of Imine to the Sm-S Bond
The first chalcogenocarboxylato lanthanid complexes, [(RCOS)3Sm(thf)2] and [Na(thf)4][Sm(RCSS)4](R = 4-MeC6H4) were isolated and characterized crystallographically. They exhibit an alkali metal salt-like reaction such as S-esterification and an insertion reaction of C=N to the Sm-S bond.
