| Popis: | Zeolitic cluster organic frameworks constructed with two different tetrahedral units, hexamethylenetetramine (hmt) and hmt-type [Cu4Cl6]2– clusters, are realized in this work for the first time. By using a tetrahedral hmt ligand to assemble in situ hmt-type Cu4Cl6 clusters, a three-dimensional cluster organic framework with lonsdaleite (lon) topology is successfully built to host the two-dimensional honeycomb-like metal–organic complex. Furthermore, a series of cluster organic frameworks based on hmt and other well-defined copper-halide clusters, such as Cu2Cl3, Cu3Cl2, Cu4Cl4, Cu5Cl6, and Cu6Cl6, are also presented, which exhibit rich topological nets. These compounds are further investigated by infrared, powder X-ray diffraction, thermogravimetric analysis, infrared and photoluminescent spectroscopy. Photoluminescent studies reveal that these compounds display yellow green emissions based on halide to metal charge transfer. This work reveals a versatile synthetic method to generate a large family of cop... |
