中文摘要	new bis (2-methoxyethylcyclopentadienyl) yttrium and ytterbium tetrahydroborates (ln = y, 1; yb, 2) have been synthesized in good yield by the reaction of bis (2-methoxyethylcyclopentadienyl) lanthanide chlorides (ln = y, yb) with sodium borohydride in thf at room temperature. the title complexes were characterized by elemental analyses, ms, h-1 nmr and ir spectra. the crystal structures of 1 and 2 have been determined by x-ray diffraction. 1 crystallizes from thf-n-hexane in space group pna2(1) with unit cell parametert: a = 1.2390(3), b = 1.1339(2), c = 1.1919 (2) nm and v = 1.6745(6) nm3 with z = 4 for d(c) = 1.39 g.cm-3.the structure was solved by direct method and refined to final r = 0.061 (for 1730 observed reflections). the space group of 2 is pna2(1) with unit cell parameters: a = 1.2399(6), b = 1.1371(5), c = 1.1897(2) nm and v = 1.6773(1) nm3 with z = 4 for d(c) = 1.72 g.cm-3, r = 0.038 (for 2157 observed reflections). the x ray structures and ir reveal the bidentate yttrium and ytterbium tetrahydroborate complexes with the intramolecular coordination bonds between lanthanide metal and ligand oxygen atoms.
