The effects of altering reaction conditions in green sonochemical synthesis of a thallium(I) coordination polymer and in achieving to different morphologies of thallium(III) oxide nanostructures via solid-state process

Abstract

In order to studies the effects of solvent and concentration of initial reagents on formation of [Tl(μ4-AB)]n (1), [HAB=4-aminobenzoic acid] coordination polymer, some experiments were designed and four samples of 1 were synthesized by sonochemical process. High concentration of initial reagents resulted in formation of compound 1 microrods. With low concentration of initial reagents, various morphologies of 1 were obtained. These four samples had been used as new precursors for preparation of thallium(III) oxide nanostructures via solid-state thermal decomposition process. One- and two-dimensional nanostructures of thallium(III) oxide can be prepared from 1. These micro and nanostructures were characterized by IR spectroscopy, X-ray powder diffraction (XRD) and Scanning Electron Microscopy (SEM).
