Abstract

Abstract A novel chalcohalide ZnHg₃Se₂Cl₄ has been synthesized through a solid state method and structurally characterized by single-crystal X-ray diffraction. It crystallizes in the acentric space group Cmc2₁ (No. 36) with cell parameters a=7.3262(8) Å, b=12.518(2) Å, c=11.3324(14) Å. The compound consists of 12-membered Hg₆Se₆ rings edge-sharing with six neighbored rings to construct a 2D layered network and the ZnCl₄ tetrahedra are sandwiched between layers. TG-DTA measurement shows that the compound is thermally stable up to 300 °C. The band gap of the crystal is about 2.23 eV, and the crystal exhibits a broad transparent range from 0.56 to 13.8 μm.
