摘要： 二苯膦基锂与6,6-二甲基富烯发生环外双键的加成反应,生成含膦取代环戊二烯基负离子(Ⅰ),它与FeCl2络合,生成1,1'-二(1-二苯膦基-异丙基)茂铁(Ⅱ).(Ⅱ)与PdCl2(PhCN)2反应,生成杂双核络合物(Ⅲ),茂铁(Ⅱ)为单斜晶系,空间群P21/c,晶胞参数a=1.3382(5)nm,b=0.8550(1)nm,c=1.7309(4)nm,β=109.16(2)°,V=1.87082nm3,Dx=1.272g/cm3,μ=5.16cm-1,F(000)=378,Z=2.31PNMR研究表明此茂铁存在分子内η5η3η1流变现象。

Abstract: Lithium diphenylphosphide reacted with 6, 6-dimethylfulvene to give addition product, phosphino-substituted cyclopentadienyl anion(I), which complexed with FeCl2, to form 1, 1′-bis[1-diphenylphosphino-isopropyl) ferrocene(Ⅱ).Compound Ⅱ reacted with PdCl2, (PhCN)2, to give heteronuclear metal complex(Ⅲ).The single crystal of Ⅱ is monoclinic, space group P21/c with a= 1.3382(5) nm, b=0.8550(1)nm, c=1.7309(4)nm, β-109.16(2)°.V=1.87082 nms, Dx=1.272 g/cm3.μ=5.16 cm-1, F(000)=378, Z=2. The study on 31p NMRshowed complex(Ⅱ)was a fluxional molecule with η5η3η1.

Key words: Phosphino-substituted ferrocene, Fe-Pd dimetal, Crystal structure, Fluxional phenomenon.
