revealed a paddle-wheel copper(II) acetate structure with tzp acting as a monodentate ligand coordinated axially. Pytc and the metal complexes showed emissive, antibacterial, and antifungal properties. Furthermore, 2 was demonstrated to be a solid-state single-source precursor to form Cu and CuO nanoparticles (NPs) under different atmospheric conditions. By transmission electron microscopy, the as-prepared
新的铜(II)配合物[Cu(Pytc)(Cl)2 ]·2H 2 O(1)和[Cu 2(tzp)2(CH 3 COO)4 ](2)(Pytc = 叔丁基2-(制备吡啶-2-基-亚甲基)肼甲酸吡啶酯; tzp = 1,2,3-三唑并[1,5- a ]吡啶),并通过元素分析,电子冲击质谱,紫外可见光谱,红外光谱和光致发光进行表征学习。的单晶X射线衍射研究2揭示了叶轮乙酸铜(II)结构,其中tzp作为轴向配位的单齿配体。Pytc和金属络合物显示出发射,抗菌和抗真菌特性。此外,已证明2是在不同大气条件下形成Cu和CuO纳米颗粒(NPs)的固态单源前体。通过透射电子显微镜,观察到所制备的纳米颗粒大致呈球形,Cu NP的平均粒径约为10–12 nm,CuO NP的平均粒径约为20–22 nm。此外,通过粉末X射线衍射图揭示了所制备的NP的高结晶度,高纯度和单相性质。
