英文摘要	用反应性熔盐法在中温(500℃)下合成KCuZrS_3.该晶体属正交晶系,空间群为Cmem,Z=4.晶胞参数,a=0.3883(7)um,b=l.444(2)um.c=1.0186(3)nm .V=0.5715(2)nm~3,D_c=5006mg·nm~(-3).M_r=430.74.F(000)=760,μ=25.217nm~(-1),λ(MoKa)=0.0710nm.R[R~2>2σ(F~2)]=0.0471.KCuZrSe_3具有层状结构.[CuZrSe_3]~-为带负电的层,按ABAB方式堆积、K~+位于相邻两层之间.Zr~(4+)与Se~(2-)成八面体配位,Cu~+与Se~(2-)...; KCuZrSe3 has been synthesized by the reactive nux method and structurally characterized by single-crystal X-ray diffraction. The crystal data: KCuZrSe3, orthorhombic, Cmcm, Z = 4, a = 0.3883 (7) nm, b = 1.4447 (2) nm, c = 1.0186 (3) nm, V = 0.5715 (2) nm(3), D-c = 5006 mg.nm(-3), M-r = 430.74, F(000) = 760, mu = 25.217 mm(-1), lambda(Mo K alpha) = 0.07107 nm, R[F-2 > 2 sigma(F-2)] = 0.0471. The crystal is bult by [CuZrSe3](-) layers separated by K+ cations. In the [CuZrSe3](-) layer, Zr4+ and Cu+ are respectively eight-four-coordinated to Se2-. K+ cations are coordinated by eight Se2- in an antitetragonal prismitic arrangment. The crystal is a thermodynamically stable phase. It is possible to synthsize the thermodynamically stable phase by reative flux reaction at intermetiate temperature.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000080498600010&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 1; 05; 497-502; 57
