本文用(C~8H~8)Y(μ-Cl)(THF)]~2与NaOC~6H~5以1:2摩尔比在四氢呋喃中反应,合成了新的中性配合物[(C~8H~8)Y(μ-OC~6H~5)(THF)]~2,经过分离,在-30℃下培养得到无色晶体,用元素分析,核磁共振和质谱进行了鉴定,并以X-射线衍射测定了晶体结构。

[(C~8H~8)Y(μ-OC~6H~5)(THF)]~2 was prepared by the reaction of [ (C~8H~8)Y(μ-Cl)(THF)]~2 and two equivalent of sodium phenolate in tetrahydrofuran. This new complex crystallized at -30℃ from THF in monoclinic space group P2~1 with unit cell parameter, a=0.9453(3), b=1.3823(3), c=1.3970(4)nm, β=97.51(3)ⅲ, V=1.8098(9)nm^3, Z=2, D~c=1.45g/cm^3. The X-ray structure analyses shows that the compound is dimeric organolanthanide complex. It is extremly sensitive to air and moisture.

Key words: CRYSTAL STRUCTURE, YTTRIUM COMPLEX, NUCLEAR MAGNETIC RESONANCE, TETRAHYDROFURAN, MASS SPECTROGRAPHY, X- RAY DIFFRACTION ANALYSIS, ELEMENTAL ANALYSIS
