Abstract: | A new three-dimensional thallium(I) supramolecular polymer, Tl2(μ2-ATA)]n (1), H2ATA = 2-aminoterephthalic acid], has been synthesized and characterized. The single-crystal X-ray data of compound 1 shows one type of TlI 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 TlI in this compound may be involved in donor bonding. Two sides of the aromatic ring of ATA2− 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). |
