Description
  • The synthesis and structure of lanthanide(III) amides containing one bifunctional beta-diketiminate ligand is reported. Compounds were obtained via a protolytic reaction of the free beta-diketimine {N-[(2-MeO) C6H5]}N=C(Me)CH=C(Me)N(H){N '-[(2-MeO)C6H5]} ((LH)-H-CO) or {N-[(2-MeO)C6H5]}N=CHCH=CHN(H) {N '-[(2-MeO)C6H5]} ((LH)-H-HO) with corresponding tris(amide) of the Ln[N(SiMe3)(2)](3) (Ln = Y, La, Nd, Sm, Eu, Gd and Yb) type in equimolar ratio at ambient temperature. Products were characterized by IR and/or multinuclear NMR spectroscopy techniques and structures of four of them have been determined by X-ray diffraction techniques. Complexes (LY)-Y-CO[N( SiMe3)(2)](2), (LLa)-La-CO[N(SiMe3)(2)](2), (LNd)-Nd-CO[N(SiMe3)(2)](2) and (LYb)-Yb-HO [N(SiMe3)(2)](2) crystalize as monomers with the six-coordinated metal centre by two amido and one tetradentate beta-diketiminato ligands. Minor hydrolytic products of composition [(LSmN)-Sm-CO(SiMe3)(2)](2)O and (L-CO)(4)O-2(OH)(4)La-4 were obtained and their structures contain two or four lanthanide atoms linked through the oxo- or hydroxo bridges. Diamagnetic complexes were tested for its potential applications in hydroamination and polymerization reactions, respectively, giving low conversion in all reactions.
