Sonochemical Synthesis of a Novel Nanoscale Hg(II) Iodobridged Coordination Polymer with Thiosemicarbazide Derivative Ligand

Infinite coordination polymers are constructed with metal ions and organic ligands as main elementary building blocks, linked by coordination bonds and other weak chemical bonds [1]. Research on coordination polymers has rapidly grown in recent years due to an increasing demand for functional materials with conducting, magnetic, nonlinear optical, porous, thermal, and fluorescence properties [2]. Nanometer-sized particles of metal coordination polymers are fascinating to explore, since their unique properties are controlled by the large number of surface molecules, which experience an entirely different environment than those in a bulk crystal. Controlling the growth of materials at the submicrometer scale is of central importance in the emerging field of nanotechnology [1]. As a continuation of the previous studies [1,2], in this work we extend our studies to investigate the interactions of universal bridging ligand(iodo anion) with Hg(II) ions in the presence of thiosemicarbazide derivative ligand (4-ptsc) and describe a simple synthetic sonochemical preparation of nano-structures of [Hg(I2)(4-ptsc)]n (1) metal-organic coordination polymer.
