Solid-state structures of para-sulfonatocalixarene with dimethylammonium and bis-6-aminohexylammonium cations are mainly based on hydrogen bond interactions. In the two complexes the calixarene molecule adopts a chair conformation with small varieties in geometry influenced by the number and types of intra- and intermolecular interactions developed by polar substituents. A stepped layer topology is induced by this chair conformation in the two complexes. Structural motifs present in the two systems generate channels, which in the first complex include dimethylformamide solvent molecules, while in the second case they include water molecules.
