A sonochemical method was used to synthesize nano-peanuts of a new lead(II) coordination 1D polymer, [Pb(qcnh)(NO)] (1), where qcnh=2-quinolincarbaldehyde nicotinohydrazide. The compound was characterized by scanning electron microscopy (SEM), elemental analysis, IR spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray powder diffraction (XRD), and single crystal X-ray analysis. The X-ray structure revealed that the Pb(II) atom is coordinated by one oxygen and three nitrogen atoms from two qcnh ligands and five oxygen atoms from three nitrate ligands in an 8+1 fashion with a PbNO donor set. One of the PdN distances in the vicinity of the central atom is a bit longer (Pb1N1=2.939(4) Å), which shows the effect of the 6s lone electron pair localized within the valence shell of the lead(II) atom. PbO nanoparticles were obtained by thermolysis of 1 at 180°C with oleic acid as a surfactant. The average diameter of the nanoparticles was estimated by XRD to be 28nm. The morphology and size of the prepared PbO nanoparticles were further studied using SEM.
采用声化学方法合成了一种新型铅（II）配位一维聚合物[Pb(qcnh)(NO)]（1）的纳米花生状颗粒，其中qcnh = 2-喹啉甲醛烟酰肼。通过扫描电子显微镜（SEM）、元素分析、红外光谱、热重分析（TGA）、差示扫描量热法（DSC）、X射线粉末衍射（XRD）和单晶X射线分析对该化合物进行了表征。X射线结构表明，Pb（II）原子以8 + 1的方式与来自两个qcnh配体的一个氧原子和三个氮原子以及来自三个硝酸根配体的五个氧原子配位，形成一个PbNO供体组。中心原子附近的一个PdN距离稍长（Pb1N1 = 2.939(4) Å），这表明了位于铅（II）原子价壳层内的6s孤对电子的影响。以油酸为表面活性剂，在180°C下热解1得到了PbO纳米颗粒。通过XRD估计纳米颗粒的平均直径为28nm。使用SEM进一步研究了制备的PbO纳米颗粒的形态和尺寸。
