Sheet Rb2HgSnS4 was synthesized solvothermally and characterized by X-ray single crystal diffraction.The compound is comprised of sheets with admantane-like[Hg2Sn2S10]8-units.The crystals belong to the space group C2/c,with the unit cell parameters a=1.1063(2)nm,b=1.1071(2)nm,c=1.5741(3)nm,a=90°,β=100.13(3)°,γ=90°.A reflectance spectroscopy study reveals the nature of the semiconductor with an energy of 2.1 eV for the compound.
