| Abstract: | Two-dimensional (2D) quaternary selenides containing cadmium mercury, K8Cd2.79Hg9.21Se16 (1) and Rb4Hg3.04Cd2.96Se8 (2), were synthesized utilizing solvothermal method. Single crystal X-ray analyses reveal that compound 1 crystallizes in the orthorhombic space group Pbcn, with a=1.082 71(17) nm, b=0.678 73(10) nm, c=1.415 0(2) nm, Z=1; compound 2 crystallizes in the orthorhombic space group Ibam, with a=0.640 72(10) nm, b=1.160 25(16) nm, c=1.452 0(2) nm, Z=2. Compound 1 contains anion layer (Cd2.79Hg9.21Se16)n8n- of eight-membered ring Cd2Hg2Se4 and six-membered ring CdHg2Se3. Compound 2 contains anion layer (Hg3.04Cd2.96Se8)n4n- of eight-membered ring Cd2(Cd/Hg)2Se4, four-membered ring CdHgSe2 and (Cd/Hg)2Se2. These two compounds were structurally characterized by scanning electron micrograph and energy-dispersive X-ray spectroscopy analysis, powder X-ray diffraction measurement, thermal analysis, solid-state optical diffuse reflectance and fluorescence properties. |
