What is another word for coronand?
Pronunciation: [kˈɒɹənˌand] (IPA) 
Coronands are cyclic polyethers that contain coordinating atoms such as nitrogen or oxygen. They are commonly used in supramolecular chemistry to bind metal ions and to form large host-guest complexes. Synonyms for coronand include crown ether, cryptand, cage compound, and macrocycle. Crown ethers are a specific subclass of coronands that have a single crown ring, whereas cryptands have multiple coordinating rings fused together. Cage compounds refer to coronands that are more three-dimensional in shape, and macrocycles describe any cyclic molecule with a large ring size. These terms are often used interchangeably to describe the various types of coronands used in supramolecular chemistry.
