| 英文摘要 | Two isostructural metal chalcogenides, hg2te2br2 (1) and hg2te2i2 (2), were obtained by solid-state reactions and structurally characterized. compounds 1 and 2 crystallize in the acentric space group p4(3)2(1)2 of the tetragonal system with eight formula units in a cell: a = 10.2388(9), c = 14.480(2) angstrom, v = 1518.0(3) angstrom(3), r-1/wr(2) = 0.0670/0.1328 for 1 and a = 10.711(3), c = 15.025(8) angstrom, v = 1724(1) angstrom(3), r-1/wr(2) = 0.0637/0.1233 for 2. both compounds are characterized by a three-dimensional (3-d) framework structure, which is composed by interconnected left-handed helices formed by both tetrahedral and trigonal hg atoms. optical absorption spectra of i and 2 reveal the presence of sharp optical gaps of 2.06 and 1.85 ev, respectively, suggesting that both materials are semiconductors. tg-dta measurements show that both compounds are thermally stable up to 200 degrees c. the composition of both compounds is well confirmed by the semiquantitative microscope analyses.
