  名称：

  Cationic monocyclooctatetraenyl-lanthanoid complexes derived from metallic lanthanoid: crystal structures of [Sm(η8−C8H8)(hmpa)3]I and [Sm(η8−C8H8)(hmpa)3][Sm(η8−C8H8)2] (HMPA = hexamethylphosphoric triamide)

  摘要：

  Addition of an excess hexamethylphosphoric triamide (abbr. HMPA) to a neutral complex SmI(eta(8)-C8H8)(thf) (1) (C8H8 = 1,3,5,7-cyclooctatetraene), which was prepared by a direct reaction of metallic samarium with C8H8 in the presence of iodine in THF, afforded a cationic samarium complex [Sm(eta(8)-C8H8)(hmpa)(3)]I (2). Complex 2 can also be prepared by a simple one-pot reaction of stoichiometric amounts of metallic samarium, cyclooctatetraene, and iodine in the presence of an excess HMPA at 50 degrees C. With a catalytic amount of iodine, ionic complexes of general formula [Ln(eta(8)-C8H8)(hmpa)(n)][Ln(eta(8)-C8H8)(2)][Ln = La and n = 4 (6); Ln = Sm and n = 3 (7)] were obtained by treating metallic lanthanum or samarium, respectively, with cyclooctatetraene in the presence of HMPA. The structure of the diamagnetic complex 6 as well as the paramagnetic complexes 2 and 7 was determined by H-1 NMR spectroscopy. Crystal structures of 2 and 7 were revealed by X-ray analyses, indicating that these complexes comprised of a cationic [Sm(eta(8)-C8H8)(hmpa)(3)](+) and an anionic part; for 2 and 7 being I- and [Sm(eta(8)-C8H8)(2)](-), respectively.
