以FeCl_2·4H_2O与(NH_4)_2MoS_4按3:1(克分子比)在DMF中反应,得到Fe(DMF)_5[(FeCl_2)_2MoS_4]。X-射线衍射单晶结构测定确定该化合物具层状结构。与笼状结构的G-系模型物相比较,指出Mg(DMF)_6~(2+)的较强成笼倾向使三核“元件”化合物Mg(DHF)_6[(FeCl_2)_2MoS_4)无法生成,据此提出Mg(DMF)_6~(2+)的笼格效应。
Fe (DMF) _5 [(FeCl_2) _2MoS_4] was obtained by the reaction of FeCl_2 · 4H_2O with (NH_4) _2MoS_4 at a molar ratio of 3: 1 in DMF. X-ray diffraction single crystal structure determination confirmed that the compound has a layered structure. Compared with the cage-like G-series model, it is pointed out that the stronger cage-forming tendency of Mg (DMF) _6 ~ 2+ can not make the ternary “component” compound Mg (DHF) _6 [(FeCl_2) _2MoS_4) , Accordingly proposed the cage effect of Mg (DMF) _6 ~ (2+).
