Synthesis, characterization and extended X-ray absorption fine structure of novel polynuclear copper complexes with new eighteen-membered macrocycle ligands

Macrocycle compounds have great importance in host-guest chemistry and moleculeidentifications. 4-acetyl-bispyrazolones are a new type of polydentate ligands. Whenthey react with diamine compounds, new compounds or complexes containing C=O andC=N groups can be obtained. These compounds can be used to study the relationship ofcoordination structure and its properties, energy transferring processes between metal

川芎嗪—Cu(Ⅱ)配合物的EXAFS测定及结构表征

川芎嗪是中草药川芎的主要有效成分.关于它与生命金属离子的作用至今未曾有人研究.本文首次合成了川芎嗪与铜(Ⅱ)的配合物.通过组分分析、红外光谱测定,并由扩展X射线吸收精细结构谱(EXAFS)的测定确证了此配合物的配位微环境,从而确定了配合物的结构.
