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.
