摘要

摘要:合成了一种新型Ru(II)多吡啶配合物[Ru(phen)2(4,4′-二羧基-2,2′-联吡啶)]PF6·1.5H2O,并用单晶x射线衍射、元素分析、电喷雾电离质谱、红外光谱、紫外光谱和发射光谱对其进行了表征。阳离子[Ru(phen)2(4,4'-(COO-),(COOH)-2,2'-bpy)]+的结构由两个phen配体和一个4,4'-二羧基-2,2'-联吡啶配体螯合的六配位钌原子组成。Ru(II)配合物的吸收光谱在紫外区表现为两个强烈的配体中心跃迁,在可见光区表现为一个金属到配体的电荷转移。该配合物在室温下可在水中发光,最大发射波长为623 nm。支持信息:Cif文件

1.3.3. Synthesis, characterization and crystal structure of a new ruthenium polypyridyl complex [Ru(phen)2(4,4'-dicarboxy-2,2'- bipyridine)]PF6
Abstract: A new Ru(II) polypyridyl complex, [Ru(phen)2(4,4'-dicarboxy-2,2'-bipyridine)]PF6·1.5H2O, was synthesized andcharacterized by single crystal X-ray diffraction, elementalanalyses, electrospray ionization mass spectrometry, infraredspectra, ultraviolet (UV) spectra, and emission spectra. Thestructure of the cation [Ru(phen)2(4,4'-(COO-),(COOH)-2,2'-bpy)]+ consists of a six-coordinated ruthenium atom chelated bytwo phen ligands and one 4,4'-dicarboxy-2,2'-bipyridine ligand.The absorption spectrum of the Ru(II) complex is characterizedby two intense ligand-centered transitions in the UV region andone metal to ligand charge transfer in the visible region. Moreover,the complex can display luminescence in water at roomtemperature, with maximum emission at 623 nm.Supporting information: Cif file
