Microstructures of [Tl2(μ2-ATA)]n (1), [HATA = 2-aminoterephthalic acid], supramolecular polymer was synthesized by sonochemical process (1S) and used as new precursor for preparation pure phase of thallium(III) oxide microstructures. [Tl(μ2-dcpa)]n (2), [Hdcpa = 2,4-dichlorophenoxyacetic acid], is another supramolecular polymer which was synthesized by green sonochemical (2S) and mechanochemical (2M) processes. These two samples of 2 were also used for preparation of thallium nanomaterials. Both processes on 2 were successful but mixture of Tl, Tl2O3 and TlCl nanostructures with various morphologies from 2S and mixture of Tl2O3 and TlCl nanoparticles from 2M were obtained. These micro and nanostructures were characterized by IR spectroscopy, X-ray powder diffraction (XRD) and Scanning Electron Microscopy (SEM).
