Huai, Wen-Juan Shen, Jin-Ni Lin, Hua Chen, Ling Wu, Li-Ming Electron-Deficient Telluride Cs<sub>3</sub>Cu<sub>20</sub>Te<sub>13</sub> with Sodalite-Type Network: Syntheses, Structures, and Physical Properties The first sodalite-type telluride, Cs<sub>3</sub>Cu<sub>20</sub>Te<sub>13</sub>, has been successfully synthesized by solid-state reactions. The single-crystal X-ray diffraction data reveal its cubic symmetry and lattice parameters of <i>a</i> = 14.7557(6) Å, <i>V</i> = 3212.8(2) Å<sup>3</sup>, and <i>Z</i> = 4. The three-dimensional network is constructed by (CuTe)<sub>12</sub> tetrakaidecahedra centered by different guest species (either a Cs<sup>+</sup> or a Te<sup>2–</sup>@Cu<sub>8</sub> cube) extending in a 2 × 2 × 2 supercell with respect to the conventional sodalite. Density functional theory analysis uncovers the unique feature of the p-type metallic sodalite framework accommodating anionic guest species, which agrees well with the experimental metallic electrical conductivity and Pauli paramagnetism. paramagnetism;CuTe;symmetry;Density;guest species;sodalite;PropertiesThe;Structures;conductivity;4.;Te;lattice;Synthese;3Cu;tetrakaidecahedra;parameter;cube;Telluride;Pauli;theory analysis uncovers;supercell;data;framework;telluride;diffraction;Physical 2014-06-02
