Metal-Chelate Dye-Controlled Organization of Cd<sub>32</sub>S<sub>14</sub>(SPh)<sub>40</sub><sup>4-</sup> Nanoclusters into Three-Dimensional Molecular and Covalent Open Architecture
architecture with conventional templating methods such as protonated amines or inorganic cations commonly used to direct the formation of porous frameworks. Herein, we report the first templated synthesis of II-VI covalent superlattices from large II-VI tetrahedral clusters (i.e., [Cd32S14(SPh)38]2-). Our method takes advantage of low charge density of metal-chelate dyes that is a unique match with

A new two-dimensional inorganic–organic hybrid solid, formulated as Cd17S4(SPh)25B(im)4 (SPh = benzenethiolate, im = imidazolate), has been synthesized under solvothermal conditions. The structure features a 63 network with 17-nuclear cadmium clusters linked by B(im)4− ligands. The compound is a semiconductor with the band gap of 2.66 eV and displays a green luminescence upon excitation at 390 nm.
Ternary supertetrahedral chalcogenolate clusters were interlinked with bipyridines into a microporous semiconducting framework with properties qualitatively different from those of the original clusters. Both the framework and the clusters were effective photocatalysts, and rapidly degraded the dye rhodamine B.
