Synthesis and Crystal Structures of Aminobis(phenolate) Lanthanocenes

The protonolysis of Cp3Ln with 1 equivalent of LH2 (LH2 = Me2NCH2CH2CH2N{CH2-(3,5-tBu2-C6H2-2-OH)}2) or salt metathesis of anhydrous LnCl3 with 1 equivalent of LNa2 and 1 equivalent of CpNa in THF afforded heteroleptic aminobis(phenolate) lanthanocene complexes of LLnCp(THF)2 (Ln = Sm(1), Er(2), Yb(3)) in good yields. Complexes 1-3 were characterized by infrared spectra, elemental analyses, and X-ray crystallography. The structural analysis indicated that the L2- ligand in each of these complexes adopt an O,N,O-tridentate coordination mode.

Reactivity of neodymium and samarium nitrides

The reaction of NdN and SmN with iodine gave the iodide-nitrides (NdI2)3N(DME)4 and (SmI)3N2(THF)2, which are inert towards sulfur, in contrast to the neodymium and dysprosium iodide-nitrid

SYNTHESIS, CHARACTERIZATION AND STUDY OF THE THERMAL STABILITY OF DIMERIC BIS(CYCLOPENTADIENYL)LANTHANIDE FURYLMETHOXIDE COMPLEXES

Four new binuclear organolanthanide alkoxides [Cp2Ln(OCH2CCHCHCHO)], (Cp=5H5; Ln = Nd, Sn, Dy, Yb) have been synthesized by simple metathetical reaction of Cp3Ln with furfuryl alcohol in THF (tetrahydrofuran) solution at room temperature. These complexes were characterized by elemental analyses, IR, XPS (X-ray photoelectron spectra) and Ms spectra, indicating that they are dimers bridged bz the oxygen atoms of furylmethoxideligands and intramolecular five-membered chelate rings formed by chelating coordinationof furan rings exist in the title complexes. The thermal stability of all the complexes has been studied and compared. It was found that the Nd and Sm complexes are thermally unstable and tend to decomposeinto Cp, Ln and Ln(OR), species upon heating.
