摘 要: 报道了由[Et4N]2WS4、CuSCN、Et4NBr和NH4SCN合成的标题簇合物[Et4N]4[WS4Cu5.5Br3.5(NCS)4(H2O)0.5]·0.5Et2O(1),并测定了其晶体结构.该晶体属三斜晶系,空间群为P-1,a=1 29581(11)nm,b=1.35388(9)nm,c=1.9644(2)nm;α=79.769(9)°,β=89.080(13)°,γ=86.063(13)°,V=3.3834(5)nm3,Z=2.该簇合物阴离子[WS4Cu5.5Br3.5(NCS)4(H2O)0.5]4-是由两个网兜状[WS3Cu3]骨架和两个"半开口"立方烷状[WS3Cu3Br]骨架组成的混合结构.W…Cu距离在0.2664(2)~0.2716(2)nm之间. The title cluster [Et_4N]_4[WS_4Cu_(5.5)Br_(3.5)(NCS)_4(H_2O)_(0.5)]·0.5Et_2O(1)was synthesized and its crystal structure was characterized by X-ray crystallography. The complex crystallizes in the triclinic space group P-1 with a = 1.295 81(11) nm, b = 1.353 88(9) nm, c = 1.964 4(2) nm; α= 79.769(9)°, β = 89.080(13)°, γ= 86.063(13)°, V = 3.383 4(5) nm^3, Z = 2. The cluster anion [WS_4Cu_(5.5)Br_(3.5)(NCS)_4(H_2O)_(0.5)]^(4-) may be described as a novel mixed framework composed of two nido-like [WS_3Cu_3] skeletons and two 'half-open' cubane-like [WS_3Cu_3Br] skeletons. The W…Cu contacts vary in the range of 0.266 4(2)~0.271 6(2) nm.
