Abstract
Two copper–organic framework supramolecular assemblies of p-sulfonatocalix[4]arene and 1,10-phenanthroline Cu2[C12H8N2][C28H20S4O16][H2O]23.5 (1) and Cu3[C12H8N2]3[C28H19S4O16]Cl[H2O]17.6 (2) were obtained by pH-dependent synthesis at room temperature. Both structures show 1D water-filled channels (rectangular shape in 1 and triangular in 2) with the solvent-accessible volume occupying 30.8% (1) and 24.2% (2) of the unit-cell volume, respectively. The calixarene molecules in both structures assume analogous cone shapes of C2v symmetry instead of the conventional C4v symmetry. Their connecting to different amounts of copper/phenanthroline cations leads to the formation of different structures.
