镧系金属高氯酸盐与1,8-萘啶氮氧化物配合物的合成、性质和结构

Synthesis, Characterization and Structure for Complexes of Lanthanide Perchlorates with 1, 8-Naphthyridine-N-oxide

本文合成了镧系金属高氯酸盐与1,8-萘啶氮氧化物形成的Ln(C_8H_6N_2O)_4(ClO_4)_3(Ln=Sm-Lu)的固体配合物。进行了元素分析、红外光谱、差热-热重分析和摩尔电导测定,并作了Eu(ClO_4)_3与1,8-萘啶氮氧化物配合物的X射线单晶结构分析。结果表明Eu^(3+)离子与4个配体的氧原子和氮原子配位,配位数为8。

The complexes of lanthanide perchlorates with 1, 8-naphthyridine-N-oxide Ln. (C_8H_6N_2O)_4(ClO_4)_3(Ln=Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) have been synthesized and characterized by elemental analyses, infrared spectra, molar conductance, differential thermal analyses (DTA) and thermogravimetric (TC). The structure of the europium complex was determined by X-ray single crystal diffraction analysis. The results show that the Eu^(3+) is coordinated by four O atoms, four N atoms belonging to four ligands. The coordination number of Eu^(3+) is eight.
