摘　　要：1982年Bailey等以三羰基环戊二烯基钼负离子钠盐与1.The title complexes were synthesized by reaction of (η-C_5H_4R) (CO)_3) Mo^-Li^+(R: H. SiMe_3.Si_2Me_5) with X(CH_2)_3X(X: Br.I) in THF. Their structures were characterized by elemental analyses.IR. ~1H NMR and ^(13)C NMR spectra. The crystal structure of η-C_5H_5(CO)_2Mo BrCO(CH_2)_2CH_2 wasdetermined by X-ray diffraction. The crystals are orthorhombic. space group P2_12_12_1. with α=0. 8600(2). b=1. 4775(3). c=1. 9900(7)nm; V=2. 529nm^3. Z=8. D_x=1. 93g·cm^(-3), μ=41. 3cm^(-1). F(000)=1424. The final deviation factor R=0. 055. R_w=0. 060.
