摘要
报道了水合三氯化铁与4',5'-二溴苯并-15-冠-5(L)固体配合物的合成.进行了元素定量分析及摩尔电导测定,并通过红外光谱、紫外光谱、差热-热重分析以及X-射线粉末衍射分析进行了性质表征.证明该配合物是1∶1型(M∶L)、非溶剂化、含有4个结晶水的化合物,属于1∶1型电解质.与三氯化铁和苯并-15-冠-5及4'-溴苯并-15-冠-5的配合物进行了性质对比,探讨了其配位作用的规律.
The new solid coordination compound of hydrated ferric chloride with 4',5'-dibromobenzo-l5-crown-5 (Br_2B15C5), hasting composition of FeCl_3·Br_2·Bl5C5 4H_2O,was synthesized in acetone medium and characterized by elemental analysis,mole conductance, IR, UV, TG-DTA, X-ray powder diffraction analysis and determination of the solubility in some general solvents. Compares the properties of the coordination compounds for ferric chloride with benzo-l5-crown-5, 4'-bro-mobenzo-15-crown-5 and 4', 5'-dibromobenzo-l5-crown-5. The thermal stability of the coordination compound between benzo-l5-crown-5 and hydrated ferric chloride is weakened after the substituents mentioned above are introduced into phenyl group. In acetonitrile solution conductivity data indicated the coordination compound behaved as 1:1 electrolytes.
