Synthesis of one-dimensional Tl2O3 nano-structures from thermolyses of a new two-dimensional thallium(I) supramolecular polymer with secondary polyhapto Tl⋯C interactions

A new thallium(I) two-dimensional supramolecular polymer, [Tl6(biphO)4(biphOH)4(NO3)2] n (1), biphOH = 4-hydroxy biphenyl, has been synthesized and characterized by elemental analyzes and IR spectroscopy. Compound 1 was structurally characterized by single-crystal X-ray diffraction and in addition to three types of TlI ions has secondary Tl⋯π Interactions. Two different Tl2O3 nano-structures have been prepared by direct calcination of 1 at two different temperatures. These Tl2O3 nano-structures were characterized by scanning electron microscopy, X-ray powder diffraction (XRD) and IR spectroscopy. This study demonstrates the coordination polymers may be suitable precursors for the preparation of nanoscale materials with various and interesting morphologies; however the final morphology of Tl2O3 can be influenced by calcination temperature.

  • ► A new Tl(I) polymer was characterized by single-crystal X-ray diffraction. ► In this polymer, all three types of TlI ions have secondary Tl⋯π Interactions. ► Different Tl2O3 nano-structures were prepared by calcination at two temperatures. ► By increase in temperature, nano particles were grown and Tl2O3 nano rods formed.
