摘要
(NH_4)_2WS_4、CuCl和PPh_3三者发生固相反应,产生棕红色固体,将此固体经CH_2Cl_2萃取和CH_3OH扩散,可得黄色柱状单晶WS_4Cu_3(PPh_3)_3Cl.晶体属三斜晶系,空间群为P,a=13.049(3),b=20.351(4),c=11.876(2),d=94.75(2)°,β=115.97(1)°,γ=74.90(2)°,Z=2.标题化合物分子是以Cu_3WS_3Cl类立方烷型簇骼为核心的分子,W-Cu的平均距离为2.719。
A brown-red solid was synthesized through a solid state reaction among (NH4)2WS4, CuCland PPh3. The solid was extracted with CH2Cl2 and then diffused with CH3OH to obtain a yellow singlecrystal WS4Cu3(PPh3)3Cl. The crystal is triclinic with a = 13. 049(3) A , b = 20. 351(4) A , c =11. 876(2) A , a=94.75(2)°, β=115. 97(1)°, r=74. 90(2)°, space group P1, z=2. The titlecompound molecule has a cluster core Cu3WS3Cl. The average distance of W- Cu is 2. 719A.
