摘要
利用电解结晶法合成了Ｋｅｇｇｉｎ结构杂多酸荷移跃迁盐（ＢＥＤＴ－ＴＴＦ）８［ＰＭｏ３ＮｂＷ８Ｏ４０］．Ｘ－射线衍射测定为单斜晶系．晶胞参数ａ＝１４．２０（０）×１０（－８）ｃｍ；ｂ＝４３．３９（０）×１０（－８）ｃｍ；ｃ＝１３．５５（６）×１０（－８）ｃｍ；β＝９１°；Ｖ＝８．３５３×１０（－２１）ｃｍ３．该化合物具半导体性质。σｒ．ｔ＝３．７×１０（－２）Ｓｃｍ（－１）．ＥＡ＝１６０ｍｅＶ．变温磁化率测定表明其为Ｓｐｉｎ－Ｐｅｉｅｒｌｓ体系．
The radical salt(BEDT-TTF)8[PMo3NbW8O40] has been prepared by electrocrystalllzation and characterized by element analysis,IR,Uv-vis,and EPR,and X-raypatten index showing a monoclinic system with a=14.20(0)×10(-8)cm,b=43.39(0)×10(-8)cm,c=13.55(6)× 10(-8)cm,β=91°,v=8.353×10(-21)cm3.σr.L=0.0375.cm(-1).EA=160meV.
