Both clusters show a very interesting structure, and consist of two parts: a nest-shaped structural unit [MOS3Cu3I2(bPy)]- and complex ion [MI(bPy)2]+. By the reaction of [Et4N]4[Mo2O2S6Cu6I6] with Phen (1,10-phenanthroline), or bPy, or bMe-bPy (4,4'-dimethyl-2,2'-bipyridyl), we prepared nest-shaped clusters [MoOS3Cu3IR2] (R = Phen, 3; R = bPy, 4; R = bMe-bPy, 5). The crystal structures of [MoI(bPy)2][MoOS3Cu3I2(bPy)] (1) and [MoOS3-Cu3I(Phen)2] (3) were characterized by X-ray diffraction. Their nonlinear optical (NLO) properties were studied with a 7-ns pulsed laser at 532 nm. Cluster 1 has large NLO absorption and NLO refraction, its α2 and η2 values were calculated as 3.0 x 10-10 m W-1 and -3.0 x 10-17 m2 W-1 in a 3.4 x 10-5 mol dm-3 DMF solution, respectively. Cluster 2 only exhibits very strong NLO absorptive property, its α2 value is 1.0 x 10-9 m W-1 when measured in a 4.8 x 10-5 mol dm-3 DMF solution. Clusters 4 and 5 have strong NLO absorption too. Their α2 values were calculated as 7 x 10-11 m W-1 and 3.5 x 10-10 m W-1, respectively. Cluster 3 only shows moderate NLO absorption, its α2 value is ~ 10-11 m W-1.
