摘要:
                                In the title complex, [Sm(C9H9F5NSi)(3)(C4H8O)], the Sm metal center is coordinated in a highly distorted tetrahedral geometry by the three N atoms of the amido ligands and by the O atom of the tetrahydrofuran ligand. Principal bond lengths include: Sm-N 2.299 (4), 2.339 (4) and 2.366 (4) Angstrom, and Sm-O 2.446 (3) Angstrom, close Sm ... F contacts of 2.536 (3) and 2.556 (3) Angstrom, and an `agostic' Sm ... C interaction of 3.154 (4) Angstrom.
