【摘要】 <正> 曾经报导过RC₂R′取代Co₂（CO）₈中两个羰基的反应,生成的双核钴簇合物常被用来作为催化中间体模拟物或是作为催化剂。已经测定了一些双核钴簇合物的晶体结构。光谱研究表明,炔烃在配位后具有和激发态的烯烃相似的几何构型。也从反应性能角度讨论了R和R′基团对双核钴簇合物的成键性及稳定性的影响。本文报导了具有较大炔烃基团的标题簇合物的合成方法和晶体结构。更多还原

【Abstract】 The cluster （C₆H₅CO₂CH₂C）₂Co₂（CO）₆ has been synthesized and characterized by element analysis, IR, ¹H NMR etc. Its crystal structure has been determined by X-ray diffraction analysis with R=0.060. The crystal is triclinic, space group P₁ with a=8.933（3）, b=11.830（6）, c=13.199（3）, α=65.64（3）°, β=84.55（3）°, γ=72.03（4）°, z=2, D_x=1.584g cm^-1 The C≡C and Co-Co form a tetrahedron with appoximate C_2V symmetry. The Co-Co bond is metl singal bond. The hybrid state of carbon atoms in the acetylene is between sp and sp².更多还原
