摘要
通过元素分析、红外光谱、核磁共振谱、热重分析、晶体结构的测定以及对化合物水解产物的分析。确认合成了下列配合物: 〔η<sup>5</sup>-2,4-（CH<sub>3</sub>）<sub>2</sub>C<sub>5</sub>H<sub>5</sub>〕LnCl<sub>2</sub>·3THF（Ln=Nd,Sm,Gd）, 〔η<sup>5</sup>-2,4-（C<sub>3</sub>H）<sub>2</sub>C<sub>5</sub>H<sub>5</sub>〕<sub>2</sub>LnCl·THF（Ln=Nd,Sm）, 〔η<sup>5</sup>-2,4-（CH<sub>3</sub>）<sub>2</sub>C<sub>5</sub>H<sub>5</sub>)<sub>3</sub>Ln（Ln=La,Sm,Gd）, (2,4-（CH<sub>3</sub>）<sub>2</sub>C<sub>5</sub>H<sub>5</sub>=2,4-二甲基戊二烯基。
The following complexes were prepared by reaction of anhydrous rare earth trichlorideswith[2, 4- (CH_3)_2C_5H_5]K and characterized by elmental analysis, IR, NMR, themal analysis,X-ray diffraction analysis as well as chemical analysis of the hydrolysis products: [2, 4- (CH_3)_2C_5H_5]LnCl_2·3THF (Ln = Nd, Sm, Gd), [2, 4- (CH_3)_2C_5H_5]_2LnCl·THF (Ln = Nd, Sm), [2, 4- (CH_3)_2C_5H_5]_3Ln (Ln = La, Sm, Gd), (2, 4- (CH_3)_2C_5H_5 = 2, 4 - dimethylpentadienyl; THF = tetrahydrofuran). The complexes are soluble in THF and insoluble in petrolum ether. They are moisture-and air-sensitive.
