双(β-二酮)开链聚醚钠铁异核配合物的研究

STUDY ON HETERO-NUCLEAR Na-Fe COMPLEXES OF AN ACYCLIC POLYETHER BEARING BIS (β-DIKETONE)

目的合成和研究双（β－二酮）开链聚醚（Ｈ２Ｌ）的碱金属ＮａⅠ与过渡金属ＦｅⅡ，ＦｅⅢ的异核金属大环配合物。方法用元素分析、红外光谱、紫外－可见光谱、室温磁化率和穆斯堡尔谱对配合物的结构进行了表征。结果在所形成的配合物［Ｎａ２Ｆｅ２ⅡＬ］２＋中，ＮａⅠ处于醚链空腔中。结论ＦｅⅡ和ＦｅⅢ分别在双（β－二酮）处配位。

Objective To synthesize and study the hetero-nuclear (Na Ⅰ and Fe Ⅱ/Fe Ⅲ) metallomacrocyclic complexes of an acyclic polyether bearing bis (β-diketone),O,O′-Bis (4-methyl-2-acetylacetone-phemyl)-triethylene glycol.Method The synthesized complexes were characterized by elemental analysis,IR,UV,magnetic moments and Mossbauer spectra at room temperture.Results Experimental data indicated that sodium ions are in the cavity composed of the polyether chain.Conclusion Transition metal ions (Fe Ⅱ or Fe Ⅲ) are coordinated with bis (β-diketone).
