Synthesis, structure and properties of a novel metal tellurobromide – Hg2TeBr3

A novel metal tellurobromide Hg2TeBr3 (1) was obtained by solid-state reactions and structurally characterized. Compound 1 is characterized by a 2D layer structure. Optical absorption spectra of 1 reveal the presence of sharp optical gap of 2.03 eV. TG-DTA measurement shows that compound 1 is thermally stable up to 173 °C. The composition of 1 is well confirmed by the semiquantitative microscope analysis.

A novel metal chalcogenide Hg2TeBr3 was synthesized via solid-state reactions. The crystal structure is characterized by a 2D layer structure, comprising of interconnected Hg-centered tetrahedral and trigons. Optical absorption spectra reveal the presence of sharp optical gap of 2.03 eV. The title compound is thermally stable up to 173 °C.Figure optionsDownload as PowerPoint slide
