| 中文摘要 | Two ternary alkali earth silver bismuthides, CaAgBi and BaAg1.937Bi2, have been synthesized by solid-state reactions of the corresponding metals in welded Nb tubes at high temperature. Their structures have been established by single-crystal X-ray diffraction studies. CaAgBi crystallizes in the hexagonal space group P6(3)mc (No. 186) with cell parameters of a = b = 4.8113(4) angstrom, c = 7.8273(9) angstrom, V= 156.92(3)angstrom(3), and Z= 2. BaAg1.837Bi2 belongs to tetragonal space group P4/nmm (No. 129) with cell parameters of a = b = 4.9202(2) angstrom, c = 1 1.628(1) angstrom, V= 281.50(3) angstrom(3), and Z= 2. The structure of CaAgBi is of the LiGaGe type, and features a three-dimensional four-connected (3D4C) anionic network with Ca2+ encapsulated in the channels formed by [Ag3Bi3] six-membered rings. BaAg1.837Bi2 is isostructural with CaBe2Ge2, a variant of the tetragonal ThCr2Si2-type structure. Its structure exhibits a three-dimensional anionic network built of (0 0 1) and (0 0 2) puckered [Ag2Bi2] layers interconnected via additional Ag-Bi bonds along the c-axis. BaAg1.837Bi2 is metallic based on band structure calculations. (c) 2006 Elsevier B.V. All rights reserved. |
