analyses. Single-crystal X-ray diffraction study shows that the structure of the silver(I) complex consists of 1D polymeric chains in which silver(I) ion is in four coordination complexes arising from one N, O-chelating L and two O, O′-bridging nitrate anions. The complex emitted energy around 360 nm and was used as a single precursor for synthesis of silver oxide nanoparticles (Ag2O NPs). From transmission
通过硝酸银 (I) 与衍生自 2-乙酰基呋喃的新腙-酰肼配体 (L) 的反应合成了组成为 [Ag(L)(NO 3 )] n的新型一维 (1D) 配位聚合物和肼羧酸乙酯。配体、L和银 (I) 配合物均使用元素分析、电子轰击质谱 (EI-Mass)、红外 (IR)、质子核磁共振 ( 1 H NMR)、紫外-可见 (UV-可见光)光谱和发射光谱分析。单晶 X 射线衍射研究表明,银 (I) 配合物的结构由一维聚合物链组成,其中银 (I) 离子位于四个配位配合物中,由一个 N、O 螯合L和两个 O, O'-桥接硝酸根阴离子。该复合物在 360 nm 附近发射能量,并用作合成氧化银纳米粒子 (Ag 2 O NPs)的单一前体。从透射电子显微镜 (TEM) 和高分辨率 TEM (HR-TEM) 图像中,所制备的 Ag 2 O NPs 的形状接近球形,平均粒径约为 22-24 nm。研究了配体和金属配合物的抗菌性能。
