A new three-dimensional thallium(I) supramolecular polymer, [Tl(μ-ATA)] (1), [HATA=2-aminoterephthalic acid] has been synthesized and characterized. The single-crystal X-ray data of compound 1 shows one type of Tl ion with a low coordination number. Compound 1 was self-assembled from Tl⋯C, Tl⋯O and Tl⋯N secondary interactions in thallium(I) coordination and the active lone pair on Tl in this compound may be involved in donor bonding. Two sides of the aromatic ring of ATA anion have been involved in two types of secondary Tl⋯C approaches. Three samples of 1 were synthesized with three different concentrations of initial reagents under ultrasonic irradiation. The thermal stability of compound 1 samples were studied by thermo gravimetric (TG) and differential thermal analyses (DTA). These nano-structures were characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM).
一种新的三维铊(I)超分子聚合物[Tl(μ-ATA)](1)[HATA=2-氨基对苯二甲酸]已被合成并进行了表征。化合物 1 的单晶 X 射线数据显示出一种低配位数的铊离子。化合物 1 是由铊(I)配位中的 Tl⋯C、Tl⋯O 和 Tl⋯N 次级相互作用以及该化合物中铊上的活性孤对电子自组装而成的,该化合物中可能涉及供体键合。ATA 阴离子的芳香环的两侧分别参与了两种类型的次级 Tl⋯C 接近。在超声辐射下,用三种不同初始试剂浓度合成了三个 1 样品。通过热重(TG)和差热分析(DTA)研究了化合物 1 样品的热稳定性。这些纳米结构通过 X 射线粉末衍射(XRD)和扫描电子显微镜(SEM)进行了表征。
