在常温的条件下,分别将2个双β-二酮席夫碱配体与银盐进行配位反应得到2个银配合物,{[Ag(L1)](Sb F6)}n(1)和[Ag2(L2)2](BF4)2(2)(L1=1,3-bis(4-methylamino-pentan-2-one)phenyl,L2=1,3-bis(3-methylamino-1-phenyl-butan-1-one)phenyl),并通过元素分析、红外光谱、粉末X射线衍射分析、单晶X射线衍射等对其结构进行了表征。结构分析表明,在配合物1中,银离子与配体L1中的2个碳原子和2个氧原子配位,形成一维链状结构,而配合物2中银离子与L2配体中的2个氧原子和2个碳原子配位,最终得到双核二聚体结构。化合物1和2都通过阴离子与结构单元之间的C-H…F作用,最终形成三维超分子结构。此外,我们还研究了化合物1、2以及配体的荧光性质。
Under normal temperature conditions, two silver complexes were prepared by coordination reaction of two double-β-diketone Schiff base ligands with silver salts, respectively. {[Ag (L1)] (Sb F6)} n (3-methylamino-1- (4-methylamino-pentan-2-one) phenyl and [Ag2 (L2) 2] (BF4) phenyl-butan-1-one) phenyl, and its structure was characterized by elemental analysis, infrared spectroscopy, powder X-ray diffraction analysis and single crystal X-ray diffraction. Structural analysis showed that in complex 1, silver ions coordinated with two carbon atoms and two oxygen atoms in ligand L1 to form a one-dimensional chain structure, whereas the amount of silver ion in complex 2 was 2 One oxygen atom and two carbon atoms coordinate, eventually resulting in a dinuclear dimer structure. Both compounds 1 and 2 act through C-H ... F between the anion and the building block to finally form a three-dimensional supramolecular structure. In addition, we also investigated the fluorescence properties of compounds 1, 2 and ligands.
