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。
In this paper, the synthesis and properties of iron-based chloride, solid state complexes of FeCl 3, CoCl 2 and NiCl 2 (both hydrates) and 4-nitro-benzo-15-crown-5 (L) The synthesized FeCl 3 · L · 2H 2 O is a new crown ether complex. Elemental analysis, infrared spectroscopy, UV spectroscopy, thermography and X-ray diffraction analysis proved to be 1: 1 type, non-solvated, containing two crystal water solid complex, and studied other related properties. Under the same conditions, neither CoCl_2 nor NiCl_2 formed complexes with 4’-nitro-benzo-15-crown-5 ligands. From which it is expected that new methods and new approaches for the separation of iron-based elements will be obtained.
