摘要： 用X射线衍射法测定了由η5-MeO2CC5H4)(CO)3MoNa和[(η5-MeO2CC5H4)(CO)2W]Fe-(CO)3Co(Co)3(μ3-S)的等瓣置换反应所生成的手性簇合物──[(η5-MeO2CC5H4)(CO)2Mo]-[(η5-MeO2CC5H4)(CO)2W]Fe(CO)3(μ3-S)的分子结构及晶体结构。晶体属P1空间群,晶胞参数α=0.87162(5)nm,b=0.76218(4)nm,c=1.87111(8)nm;α=94.164(4)°,β=97.979(2)°,γ=99.108(2)°,Z=2,μ=5.9cm-1.最终的一致性因子R=0.036,Rw=0.037.该簇合物含MoWFeS四面体簇核,其中Mo、W原子以1:1的比例无序地分占了四面体的2个顶点。

Abstract: The molecular structure of[(η5-MeO2CC5H4)(CO)2MO][(η5-MeO2CC5H4)(CO)2W] Fe(CO)3(μ3-S), prepared through isolobal displacement reaction between η5-MeO2CC5H4)(CO)3MONa and [(η5-MeO2CC5H4)(CO)2W]Fe(CO)3Co(Co)3 (μ3-S) has been determined by X-ray diffraction technique.The crystal belongs to triclinic space group P1 with α=0.87162(5) nm,b=0.76218(4) nm,c=1.87111(8)nm,α=94.164(4)°,β=97.979(2)°γ=99.108(2)°,Z=2,μ=5.9cm-1.The final agreement factor R=0.036 for 4180 observed reflectional points.There is a tetrahedral MoWFeScluster core in the molecule of this complex with Mo and Woccupying two apexes disorderly in the ratio of 1:1.
