摘要：
The reaction of Cu(MeCN)(4)[ClO4], dppm (bis(diphenylphosphino)methane) and [Et4N](2)[WSe4] in DMF-CH2Cl2, affords the cationic cluster [WSe4{Cu(dppm)}(4)](2+) whose structure was shown by X-ray analysis that four edges of the tetrahedral WSe4 core are bridged by a square arrangement of four Cu(I) atoms with the dppm ligands bridging the edges. The cluster compound exhibits a strong optical limiting effect with threshold of 0.3 J.cm(-2).
