Abstract: | Solvothermal reactions of [Et(4)N][Tp*WS(3)(CuCl)(3)] (1) (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) with CuCN and KCu(CN)(2) afforded two [Tp*WS(3)Cu(3)]-based coordination polymers [Tp*WS(3)Cu(3)(μ(3)-DMF){Cu(CN)(3)}](2) (2) and K[Tp*WS(3)Cu(3)(μ(3)-DMF){Cu(2)(CN)(4.5)}](2) (3). The third-order NLO and PL responses of 1 were activated and greatly amplified through its assembly via the [Cu(CN)(3)](2-) and [Cu(4)(CN)(9)](5-) species in 2 and 3. |
