摘要

超分子配位化合物作为合成化学和材料科学之间的重要接口,受到了广泛的研究。镧(III)与配体1,4-二(3-吡啶基)-2,3-二氮杂-1,3-丁二烯(3-bpdb),[La(3-bpdb)1/2(H2O)4(NO3)3]2.H2O的新型双核11配位配合物的纳米结构用声化学方法合成了3-bpdb(1),并通过x射线粉末衍射、FT-IR光谱和扫描电镜对其转化进行了验证。单晶x射线分析表明,其晶体组成属于三斜空间群p_。对这种化合物的晶体结构进行了研究。此外,化合物1已被用作合成La2O3纳米结构的前驱体。采用SEM、FT-IR和XRD对La2O3纳米结构的结晶度和形貌进行了表征。

Sonochemical Syntheses and Structural Elucidation of New Dinuclear Lanthanum (III) Complex: Precursors for La2O3 Nanostructure
Supramolecular coordination compounds have been widely surveyed as they represent an important interface between synthetic chemistry and materials sciences. Nanostructure of a new dinuclear 11-coordinated complex of lanthanum(III) with the ligand 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene(3-bpdb),[La(3-bpdb)1/2(H2O)4(NO3)3]2.H2O.3-bpdb (1), was synthesized by a sonochemical method, and these transformations have been verified by X-ray powder diffraction, FT-IR spectroscopy, and scanning electron microscopy. Crystal composition as determined by single-crystal X-ray analysis reveals that it belongs to the triclinic space group Pī. The crystal structure of this compound has been studied. Also, compound 1 has been used as a precursor of the synthesis of La2O3 nanostructure. The crystallininty and morphology of the La2O3 nanostructure were characterized by SEM, FT-IR and XRD.
