| Abstract: The title cluster compound [WS4Cu3Br(bipy)2] has been synthesized by the reaction of (NH4)2[WS4]， CuBr and 2，2′-bipy in DMF solution. Single crystal X-ray diffraction data show that the compound has a nest-shaped structure. Nonlinear optical properties (NLO) of the cluster were investigated by a Z-scan technique with a pulsed laser at 532nm. The cluster exhibits the strong NLO absorption and a self-defocusing effect (effective non-linear absorption coefficient， α2eff=7.3×10-11mW-1; effective non-linear refractive index， n2eff=3.9×10-11esu) when measured in a 6.0×10-4mol·dm-3 DMF solution.
