铁系元素冠醚配合物的研究--Ⅰ.铁系氯化物与4''-硝基-苯并15-冠-5配合物的合成和性质

本文报导铁系氯化物,FeCl_3、CoCl_2和NiCl_2(均为水合物)与4—硝基—苯并—15—冠—5(L)固态配合物的合成和性质。 合成的FeCl_3·L·2H_2O是一种新的冠醚配合物。经元素分析、红外光谱,紫外光谱、热谱及X—射线衍射分析证明是1:1型,非溶剂化、含有两个结晶水的固态配合物,并且研究了其他有关性质。 在同样条件下,CoCl_2和NiCl_2皆不与4′—硝基—苯并—15—冠—5配体生成配合物。从中可望得到铁系元素分离的新方法和新途径。

STUDIES ON IRON SERIES COORDINATION COMPOUNDS WITH CROWN ETHER--I. SYNTHESES AND PROPERTIES OF IRON SERIES METAL HALIDES WITH 4''-NITRO-BENZO-15-CROWN-5ETHER SOLID COORDINATION COMPOUNDS

This paper reports the syntheses aad properties of iron series metal halides (FeCl₃, Co₂Cl₂ and NiCl₂) with 4'-nitro-benzo-15-crown-5 ether solid coordination compounds.Synthetic FeCl₃·L·2H₂O is a new kind of crown ether coordination compound. It is coordination compound of 1:1 type, nonsolvate, but contains two moles crystal water, identified by element analysis, IR spectrum, UV spectrum,DTA,TG,and X-ray. Its m.p. and solubility have been detected.Under the same conditions, Co₂Cl₂ and NiCl₂ do not ebordinate with 4-nitro-benzo-15-crown-5 ether, thereby, a new approach and method are provided to separate the iron series.
