Abstract: Layered K2CdSnS4 (1) was synthesized solvothermally and characterized by X-ray single crystal diffraction. The crystals belong to the space group C2/c, with a=1.1021(5) nm, b=1.1030(5) nm, c=1.5151(10) nm, α=90°, β=100.416(12)°, γ=90°, V=1.8114(17) nm3, Z=8, Dc=3.209 g·cm-3, Mr=437.60, μ=6.853 mm-1, F(000)= 1600, λ=0.071073 nm, and the final R=0.1042 and wR=0.2008 for all observed reflections. The compound is comprised of sheets with adamantane-like [Cd2Sn2S10]8- units. UV-Vis reflectance spectrum of compound 1 reveals that 1 is a semiconductor with a band gap of 2.2 eV. CCDC: 424763. |
