Monomere bis(η5-cyclopentadienyl)lanthanoid(III)-komplexe mit raumerfüllenden alkoxid- und thiolat-liganden: Molekülstruktur von (C5H5)2Yb(THF)[SC6H2(CF3)3-2,4,6]
摘要:
2,4,6-Tris(trifluoromethyl)phenol (R(F)OH) reacts with (C5H5)(3)Ln (Ln = Nd, Sm, Yb) to give the mononuclear bis(cyclopentadienyl)lanthanide alkoxides (C5H5)(2)Ln(THF)(OR(F)) [Ln = Nd (1), Sm (2), Yb (3); R(F) = 2,4,6-tris(trinuoromethyl)phenyl]. Similarly, (C5H5)(2)Yb(THF)(SR(F)) (4) is obtained upon treatment of (C5H5)(3)Yb with 1 equiv. of R(F)SH. The molecular structure of 4 was determined by X-ray diffraction. Compound 4 is the first mononuclear bis(cyclopentadienyl)lanthanide (III) thiolate complex.
