An enantiomerically pure propeller-shaped supramolecular capsule based on the stereospecific self-assembly of two chiral tris(oxazoline) ligands around three Ag-I ions
Self-Recognition of ligand chirality leads to the completely stereospecific self-assembly of a propeller-shaped supramolecular capsule induced by a rigid chiral tris(oxazoline) acting as a tris-monodentate ligand and AgI metal ions having a tetrahedral coordination geometry (the structure of one helical complex is shown).
