摘要
本文通过二茂基镧系金属氯化物Cp_2LnCl(Cp=C_5H_5;Ln=Dy,Yb)与烷基醇ROH(R=-CH_2CH_2CH_3,-CH_2CH=CH_2)在四氢呋喃中反应,合成了四个新的含三种不同配位基的镧系金属有机化合物;元素分析、红外光谱及质谱分析表明这些化合物可能具有三聚体结构,即:[CpLn(OR)Cl]_3.
By reaction of Cp2LnCl(Cp = C5H5; Ln = Dy, Yb) with ROH(R = -CH2CH2CH3, -CH2CH = CH2) in THF (tctrahydrofuran) at room temperature, four new mixed ligand organolanthanidc compounds involving three different ligands (namely, cyclopcntadienyl, alkoxidc and chloride anion) have been synthesized. All the compounds were characterized by elemental analysis, infrared and mass spectra, indicating that they are possibly trimeric. Their general formula is [CpLn(OR)Cl]3.
