用格氏试剂还原(NH_4)_2MoS_4和FeCl_3,然后在DMF中重结晶,得到化合物(Mg·6DMF)[MoFeS_4Cl_2]的晶体。用X射线衍射测定了该化合物的晶体结构。晶体属三斜晶系。空间群C_1~1-P1。晶胞参数a=11.245,b=9.440,c=9.256,α=86.89°,β=71.44°,γ=75.28°。每个单胞含一个分子。结构经最小二乘法修正后,偏离因子为0.050。阴离子呈螺旋桨型扭变,被包合在阳离子(Mg·6DMF)~(2+)密堆积而成的笼状空腔中。
The Grignard reagent was used to reduce (NH_4) _2MoS_4 and FeCl_3 and then recrystallized from DMF to obtain the crystal of compound (Mg · 6DMF) [MoFeS_4Cl_2]. The crystal structure of the compound was determined by X-ray diffraction. Triclinic crystal system. Space group C_1 ~ 1-P1. The unit cell parameters a = 11.245, b = 9.440, c = 9.256, α = 86.89 °, β = 71.44 °, γ = 75.28 °. Each unit cell contains a molecule. After the structure was modified by the least squares method, the deviation factor was 0.050. The anion is twisted in the form of a propeller and enclosed in a cage-like cavity formed by the close packing of the cation (Mg · 6DMF) 2+.
