摘　　要：Reaction of (NH4)2WOS3 with CuI and 4-tert-butylpyridine (4-bpy) in EtOH afforded a tetranuclear neutral cluster WOS3Cu3I(4-bpy)3·0.25EtOH. This compound was characterized by elementary analysis, IR, 1H NMR, TGA, and its crystal structure was determined by X-ray single crystal diffraction. It belongs to monoclinic, space group P2/c with a=2.220 9(2) nm, b=1.364 66(11) nm, c=2.490 6(2) nm, β=104.953(2)°, V=7.292 9(12) nm3, Z=4. The title compound may be viewed as having a half-open cubane-like structure in which three Cu(4-bpy)+ units are linked by a triply-bridging WOS32- unit and a doubly-bridging iodine atom. CCDC: 266412.Reaction of （NH4）2[WOS3] with CuI and 4-tert-butylpyridine （4-bpy） in EtOH afforded a tetranuclear neutral cluster [WOS3Cu3I（4-bpy）3]·0.25EtOH.
