- W788319699 abstract "In this thesis, we synthesized the quaternary selenide by the solid-state reaction at 823 K. The structures were determined with single crystal X-ray diffraction. In addition, we also carried out the measurements of the physical properties. Three selenide, namely Ag2.92(2)Ge1.15(3)Sb6.92(2)Se13, Ag3.3(3)Ge2.3(1)Sb7.4(3)Se15 and Ag4.72(2)Ge0.56(2)Sb8.72Se16, adopted the pavonite-typed structure with different order number N. All selenides crystallized in monoclinic crystal system: the space group of Ag2.92(2)Ge1.15(3)Sb6.92(2)Se13 was C2/m and its cell parameters were a = 13.5656(8) A, b = 4.0940(2) A, c = 22.020(1) A, = 91.739°, V = 1222.4(1) A3, Z=2; while the space group of Ag3.3(3)Ge2.3(1)Sb7.4(3)Se15 and Ag4.72(2)Ge0.56(2)Sb8.72Se16 was Cm and theirs cell parameters were a = 13.510(2)/13.579(2) A, b = 4.0844(3)/4.0935(7) A, c = 26.328(3)/27.392(5) A, = 104.82(1)/96.513(4)°, V = 1404.4(3)/1512.8(4) A3, Z=2/2, respectively. Ag4.72(2)Ge0.56(2)Sb8.72Se16 is the one with the largest order number N in the pavonite homologous series; and these three selenides, which were synthesized in the same system for different order number N, were rare in pavonite series. The measurements of the physical properties showed the three selenides had semiconductor behaviors." @default.
