摘要

The heterobimetallic peralkylated complexes [Ln(AlR4)(2)](n) (Ln = Sm, Yb; R = Me, Et) were synthesized by a silylamide elimination route from Ln[N(SiMe3)(2)](2)(THF)(2) and an excess of AlR3. The solid-state structure of [Sm(AlEt4)(2)](n) is isomorphous to that of the ytterbium derivative. Polymeric [Yb(AlMe4)(2)](n) was examined by H-1 and C-13 MAS NMR spectroscopy revealing the presence of distinct bridging methyl groups. The reaction of [Yb(AlMe4)(2)](n) and 1,10-phenanthroline ( Phen) afforded the monomeric donor adduct Yb(AlMe4)(2)( Phen), while the protonolysis reaction with 2 equiv. C5Me5H ( HCp*) yielded a separated ion pair of composition [Cp*Yb(THF)(4)][AlMe4]. Single-crystal X-ray diffraction data are provided for both ytterbium(II) complexes. Solid- state magnetic measurements ( SQUID) were performed on [Sm(AlMe4)(2)](n), [Sm(AlEt4)(2)](n), SmI2(THF)(2) and Sm[N(SiMe3)(2)](2)(THF)(2) showing high effective magnetic moments 3.67 mu(B) < mu(eff) < 4.43 mu(B).
