本文合成了镧、铈、镨、钕硝酸盐与1,8-萘并-16-冠-5组成为1:1的固体配合物。对这些化合物进行了元素分析、X-射线物相分析、红外光谱、热重和差热分析。经X-射线结构分析证明,它们是一类新的、11-配位的镧系元素冠醚配合物。
In this paper, a solid complex of lanthanum, cerium, praseodymium, neodymium nitrate and 1, 8-naphthalene-16-crown-5 was synthesized. These compounds were subjected to elemental analysis, X-ray phase analysis, infrared spectroscopy, thermogravimetry and differential thermal analysis. X-ray structure analysis proved that they are a new class of 11-coordinated lanthanide crown ether complexes.
