铁磷硫簇合物(μ-Me_2P)(μ-t-Bus)Fe_2(CO)_6的单晶分子结构

Crystal and Molecular Structure of Iron-Phosphorous-Sulfur Cluster Complex(μ-Me_2 P)(μ-t-BuS)Fe_2(CO)_6

铁磷硫簇合物(μ-R_2P)(μ-RS)Fe_2(CO)_6是一种混合配体桥连的羰基铁配合物,它既可以看作是铁磷簇合物(μ-R_2P)_2Fe_2(CO)

The crystal of (μ-Me_2P) (μ-t-BuS)Fe_2(CO)_6 belongs to triclinic space group P1with a=0.9049(3),b=1.3816(3),c=1.5706(4)nm:α=102.89(1)°,β=106.27(2)°,γ=93.03(2)°;V=1.8233nm^3;Z=4;D_c=1.56g/cm^3;F(000)=178.97.The structural comparison has been made among the butterfly-shaped cluster core Fe_2PSof (μ-Me_2P)(μ-t-BuS)Fe_2(CO)_6,the cluster core Fe_2P_2 of (μ-Me_2P)_2Fe_2(CO)_6 and the clus-ter core Fe_2S_2 of (μ-EtS)_2Fe_2(CO)_6.The t-butyl group on the cluster core Fe_2PS Is attachedto sulfur by an e-type of bond while two methyl groups attached to phosphrous by a- ande- types of bonds.This is in good agreement with the assignment according to 1~H NMR spe-ctroscopy.
