【摘要】 以（NH₄）₃VS₄为起始原料,用低温固相法合成了标题簇合物,并测定其晶体结构.晶体属空间群P（?）,单胞参数a=1.3139（10）,b=2.5113（17）,c=1.1800（8）nm,α=93.04（6）β=114.86（5）,γ=96.71（7）,Z=2,μ=21.4cm^-1,R=0.084.在簇合物中,VS₄^3-保持较严格的四面体构型,并螯合四个Cu（I）离子连同桥Br-离子形成具有额外面的立方烷簇骼[VS₄Cu₄Br].更多还原

【Abstract】 The title compound was prepared by solid state reaction of the mixture with mole-ratio (NH4)3VS4: CuCl: PPh,: Et4NBr = 1: 2: 3: 1 at 100℃, 12 hours. The crystal structure was determined from single crystal X-ray diffraction data. It crystallizes in triclinic, space group P1, a = 1.3139(10), b = 2.5113(17), c = l. 1800(8 )nm, α= 93.04(6), β=114.86(5), γ=96.71(7)°, Z = 2, μ= 21.4cm-1, R = 0.084. In the title cluster, VS43- retain more serious tetrahedral configulation and chelates with four Cu(Ⅰ) ions together with bridged Br- formed a cubane with an extra face [VS4Cu4Br] core.更多还原
