A d10Cu(I) two‐dimensional (2D) metal–organic framework (MOF) with chemical formulas, {[Cd(L)(tcm)(H2O)]⋅2H2O}n(1) (L = 1,3,5‐tris(4‐pyridylethynyl)benzene; tcm−1= tricyanomethanide) was synthesized and structurally characterized by single crystal X‐ray diffraction method. In 1, the coordination geometry of Cu(I) ion is distorted tetrahedral coordinated to four N atoms from three L and one tcm−ligands. A 2D puckered honeycomb‐like layer is formed via the bridges of Cu(I) ions and L ligands with tris‐monodentate coordination mode. Two 2D layers are mutually interpenetrated via the π–πstacking interaction between benzene ring of L ligand and pyridyl ring of neighboring L ligand to form a two‐fold interpenetrated 2D net and then arranged orderly to construct its 3D supramolecular network. Thermal stability and in‐situ temperature‐dependent structural variations of 1are performed by TG analysis associated with temperature‐dependent PXRD measurement. The water vapor ad‐/de‐sorption isotherm and CO2adsorption isotherm of 1are measured and discussed. A d10Cu(I) supramolecular architectures, {[Cd(L)(tcm)(H2O)]⋅2H2O}n(1), has been assembled by 2D puckered honeycomb‐like layered MOF by using a tripodal ethynyl‐based pyridyl ligand (L), showing interesting water ad‐/de‐sorption isotherm. |
