A
molecular entity comprising a monocyclic ligand assembly that contains three or more
binding sites held together by covalent bonds and capable of binding a
guest in a central (or nearly central) position. The
adducts formed are sometimes known as '
coronates'. The best known members of this group are macrocyclic polyethers, such as '
18-crown-6', containing several repeating units
–CR2–CR2O–
(where R is most commonly H), and known as crown
ethers.
