Abstract

Solvothermal reactions of [Et4N][Tp*WS3(CuCl)3] (1) (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) with CuCN and KCu(CN)2 afforded two [Tp*WS3Cu3]-based coordination polymers [Tp*WS3Cu3(μ3-DMF){Cu(CN)3}]2 (2) and K[Tp*WS3Cu3(μ3-DMF){Cu2(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 [Cu4(CN)9]5? species in 2 and 3.
