Reaction of [Et4N][Tp∗WS3] (1) with [Cu(MeCN)4]PF6, CsCl, isonicotinic acid and CuCN, and treatment of [Et4N][Tp∗WS3(CuCl)3] (2)/[Et4N][{Tp∗WS3Cu3Cl}2(μ-Cl)24-Cl)] (3) with AgOTf and bpp (Tp∗ = hydridotris(3,5-dimethylpyrazol-1-yl)borate; bpp = 1,3-di(4-pyridyl)propane) give rise to [Et4N]2[{Tp∗WS3Cu3(CN)0.5}2(μ-Cl)24-Cl)]2(PF6)2 (4) and [(Tp∗WS3Cu3)23-Cl)2(bpp)3]2(OTf)4 (5), respectively. Compounds 4 and 5 feature cluster-based rectangle and [2]catenane architecture, and both exhibit enhanced third-order nonlinear optical responses relative to those of 1.
