The crystal structure of a 16-residue aromatic oligoamide that folds into a compact helix containing a 9-Å inner pore. A sodium ion is complex at the center of the pore through a first coordination sphere consisting of water and methanol, and a second coordination sphere made of amide carbonyl oxygens.
