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.
