摘要/Abstract

摘要：

采用常规方法合成了3种Fe（Ⅲ）配位超分子配合物：［Fe(phen)₃］［Fe(ox)₃］·KOH·6H₂O(1), ［Fe(en)₂(ox)］［Fe(en)(ox)₂］·2H₂O(2), K₃(glycol)·(Fe_0.2Cr_0.8)(ox)₃(3)(phen=邻二氮杂菲, en=乙二胺, ox=草酸). 通过X射线单晶衍射、红外光谱（IR）、紫外可见吸收光谱（UV-Vis）对配合物进行表征, 并测定了它们在4.5~300 K的变温磁化率. 研究结果表明, 在低温区配合物1~3均表现出弱的反铁磁性质, 其中配合物2的反铁磁性最强.

关键词: Fe(Ⅲ)配合物；晶体结构；光谱；磁性

Abstract:

Three Fe（Ⅲ）coordination supramolecules ［Fe(phen)₃］［Fe(ox)₃］·KOH·6H₂O(1), ［Fe(en)₂(ox)］［Fe(en)(ox)₂］·2H₂O(2), K₃(glycol)·(Fe_0.2Cr_0.8)(ox)₃(3),(phen=phenanthroline, en=ethylenediamine, ox=oxalate acid) were synthesized. The crystal structures of the complexes were determined by Xray single crystal diffraction, and the complexes were characterized by IR, UVVis and magnetic susceptibility. At a low temperature compounds 1~3 all show antiferromagnetism, compound 2 shows the highest antiferromagnetism.

Key words: Fe（Ⅲ）coordination supramolecule, crystal structure, spectra, magnetic
