无水FeCl_3和格氏试剂在THF中反应,反应产物在DMF中重结晶,得到(Mg·6DMF)[(FeCl_3)_2O]的晶体,在NMF中重结晶,得到FeCl_3·3NMF。本文讨论了氧桥生成的条件。(Mg·6DMF)((FeCl_3)_2O]和(Et_4N)_2[MoFeS_4Cl_ 2)在DMSO中反应得到一非化学计量的笼状化合物,其分子式为[MoFeS_4Cl_2]。[Fe_2S_2Cl_4]_(1-a)(Fe·6DMSO)_b(Mg·6DMSO)_(1-b。) 分别测定了(Mg·6DMF)((FeCl_3)_2O]及其衍生物的晶体结构。首次发现了单氧桥二铁化合物的交错型四配位直线氧桥结构,它存在于(Mg·6DMF)~(2+)的笼状母体中。 (Fe·6DMSO)~(2+)统计分布于(Mg·6DMSO)~(2+)的笼状骨架上,而阴离子[MoFeS_4Cl_2]~(2-)和[Fe_2S_2Cl_4]~(2_)统计分布在这个笼状母体中。 在FeCl_3·3NMF中,可以看到Fe—Cl键的对位效应。
Anhydrous FeCl 3 and Grignard reagent are reacted in THF, and the reaction product is recrystallized from DMF to obtain a crystal of (Mg · 6DMF) [(FeCl 3) 2 O], which is recrystallized from NMF to obtain FeCl 3 · 3NMF. This article discusses the conditions for oxygen bridge formation. The reaction of (Mg · 6DMF) ((FeCl_3) _2O] with (Et_4N) _2 [MoFeS_4Cl_2] in DMSO gave a non-stoichiometric cage compound with the molecular formula of [MoFeS_4Cl_2]. The crystal structure of (Mg · 6DMF) ((FeCl_3) _2O] and its derivatives were determined by [Fe_2S_2Cl_4] _ (1-a) (Fe · 6DMSO) _b (Mg · 6DMSO) _ (1-b. The intercalated tetracoordinate linear oxygen bridge structure of monooxo-bridged di-iron compounds was found, which exists in the cage matrix of (Mg · 6DMF) ~ (2+). (Fe · 6DMSO) ~ (2+) In the framework of (Mg · 6DMSO) ~ (2+) cage, the anions [MoFeS_4Cl_2] ~ (2-) and [Fe_2S_2Cl_4] ~ 2_ were statistically distributed in this cage-like matrix.In FeCl_3.3NMF, You can see the Fe-Cl bond effect.
