Synthesis and characterization of nano-scale of a new thiocyanate Hg(II)

Mercury plays an important role in biological and chemical processes. It also forms useful amalgams with many metals, which find various applications in diverse fields. Due to the numerous applications and the toxic nature of amalgams and mercury compounds, there is a need for simple and accurate analytical methods that allow for the rapid determination of mercury content in samples [1-3]. Mercury is one of the most toxic heavy metals on earth. Nano-scale and single crystal of a new Hg(II) complex, {[Hg(2,6-pdcaH)(SCN)(H2O)]},{2,6-pdcaH2 = 2,6-Pyridinedicarboxylic acid } has been synthesized by the reaction of mercury chloride, Sodium thiocyanate and 2,6-pdcaH using sonochemical and heat gradient methods, respectively. The new nanoparticles were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and FT-IR spectroscopy. Complex was structurally characterized by single crystal X-ray diffraction.
