Scope note: Poliéteres macrocíclicos con una unidad de repetición (-CH2-CH2-O)n, donde n es mayor que 2 y algunos oxígenos pueden estar sustituídos por nitrógeno, azufre o fósforo. Estos compuestos son útiles para coordinar CATIONES. La nomenclatura emplea un prefijo para indicar el tamaño del anillo y un sufijo para el número de heteroátomos.

Scope note: Macrocyclic polyethers with the repeating unit of (-CH2-CH2-O)n where n is greater than 2 and some oxygens may be replaced by nitrogen, sulfur or phosphorus. These compounds are useful for coordinating CATIONS. The nomenclature uses a prefix to indicate the size of the ring and a suffix for the number of heteroatoms.
