资源简介:
Two novel layer structure compounds, Cs2HgSb4S8 and Cs2Hg2Sb2Se6, were synthesized in organic solvent under solvothermal conditions. The Cs2HgSb4S8 is formed of [HgSb4S8]2– ribbons and S atoms by corner sharing. The Cs2Hg2Sb2Se6 is made up of [SbHg2Se6]5– ribbon and disorder trigonal-pyramidal SbSe3 by sharing μ3-Se. These compounds are characterized by single-crystal X-ray diffraction, powder X-ray diffraction, solid-state optical absorption spectra, and so on.
