(NH_4)_2MoS_4和FeCl_3用格氏试剂还原后,反应产物在DMSO中重结晶,得到不具催化还原活性的(Mg·6DMSO)[MoFeS_4Cl_2]的晶体。X射线衍射测得其空间群力C_1~1-P_1~-;单胞参数。a=10.306,b=9.969,c=8.591,α=89.02°,β=89.75°,γ=86.74°结构参数经最小二乘法修正,偏离因子为0.064。晶体中阴离子是两个共棱的四面体桥联而成的二核簇合物,它被包合在络合阳离子密堆积而成的笼状母体中。这个笼状骨架比较松散,对被包合的阴离子有一定的选择性。 After reduction of (NH 4) 2 MoS 4 and FeCl 3 with Grignard reagent, the reaction product was recrystallized from DMSO to obtain crystals of (Mg · 6DMSO) [MoFeS 4 Cl 2] with no catalytic reduction activity. X-ray diffraction measured its space group force C_1 ~ 1-P_1 ~ -; cell parameters. a = 10.306, b = 9.969, c = 8.591, α = 89.02 °, β = 89.75 °, γ = 86.74 ° The structure parameters were corrected by the least squares method with a deviation factor of 0.064. Anions in the crystal are two core-cluster compounds bridged by two co-prism tetrahedra and are enclosed in a cage-like matrix that is closely packed with complex cations. This cage-like skeleton is loose and has some selectivity for the anions that are encased.
