摘要： (NH4)2WS4、CuCl和(n-Bu)4NBr在Ar气氛中,90℃下反应10h,所得产物先后经CH2Cl2与CH3OH处理,得一桔红色晶体。该晶体与吡啶反应,即得到桔红色针状晶体[WS4Cu2(Py)4],属单斜晶系,空间群C2/c,晶胞参数:a=14.109(1)Å,b=12.704(1)Å,c=14.071(1)Å;β=96.97(1)°;Z=4。结构用重原子法解出,经最小二乘法修正,偏离因子R=0.027。

Abstract: The reaction among (NH4)2WS4, CuCl and (n-Bu)4NBr yields red-orange crystal. The Crystal reacts with excess of pyridine to produce red-orange crystal [WS4Cu2(Py)4]. It belongs to the monoclinic system, space group C2/c,with a=14.109(1)Å, 6=12. 704(1)Å, c=14. 071(1)Å; β=96. 97(1)°; V=2504.1Å3 and Z=4. The intensity data were collected by ENRAF-NONIUS CAD4 diffractometer. The molecular structure was solved by patterson method and Fourier method and refined by least-squres with anisotropic thermal parameters. The value of Ris 0.027.
