含2,2'-联吡啶配体簇合物的合成、晶体结构及非线性光学性质

Synthesis, Crystal Structure and Nonlinear Optical Propertiesof Cluster Compound Containing 2,2′-Bipyridine as Ligand

The Cluster compound [Cu3BrWOS3(bipy)2] was synthesized by reaction of (NH4)2WOS3, CuBr, 2,2′ bipyridine and n Bu4NBr at room temperature and characterized by IR, UV and elemental analyses. The structure of [Cu3BrWOS3(bipy)2] wasdetermined by single crystal X ray diffraction revealing that the cluster consist of a nest shaped core. The W atom is tetrahedrally coordinated by three S atoms and one O atom. There are two types of copper atoms in the WOS3Cu3 aggregate: two copper atoms are tetrahedrally coordinated and another copper atom is trigonally coordinated. The nonlinear optical properties were studied with an 8ns pulsed laser at 532nm. Its optical responses to the incident light exhibit considerably optical absorptive and strong self focusing effect with α2=0.90×10-10m·W-1, n2=2.72×10-18m2·W-1. CCDC: 196348.
