摘　　要：Treatment of a W/Cu/S precursor[Et_(4)N][Tp*WS_(3)(CuBr)_(3)](1)with three equiv.of CuCN in DMF/MeCN/benzonitrile(or α-tolunitrile)yielded two[Tp*WS_(3)Cu_(3)(μ_(3)-DMF)]-based coordination polymers,[Tp*WS_(3)Cu_(3)(μ_(3)-DMF)(CN)_(3)Cu]_(2)•2DMF(2•2DMF)and[Tp*WS_(3)Cu_(3)(μ_(3)-DMF)(CN)_(3)Cu(α-tolunitrile)]_(2)•3MeCN(3•3MeCN),respectively.Structural analysis revealed that 2 adopts a 2D network with a 4.8^(2) topology while 3 has a 1D ladder-type chain.The third-order nonlinear optical responses of 2 and 3 in DMF were 10 times enhanced compared to those of the precursor cluster 1.
