text: In supramolecular<unk> ,<unk>  describes complexes that are composed of two or more molecules or ions held together in unique structural relationships by hydrogen bonding or by ion pairing or by Van der Waals force other than those of full covalent bonds.
  The<unk>  component is defined as an organic molecule or ion whose binding sites converge in the complex and the<unk>  component is defined as any molecule or ion whose binding sites diverge in the complex.
