The title compound was prepared by solid state reaction of the mixture with mole-ratio (NH4)3VS4:CuCl:PPh3: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=1.1800(8), 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, VS4^3^- retain more serious tetrahedral configulation and chelates with for Cu(I) ions together with bridged Br^- formed a cubane with an extra face [VS4Cu4Br]core.
