questi composti, è formata dal gruppo -OCH<sub>2</sub>CH<sub>2</sub>-. Derivano il nome dal fatto che le loro configurazioni più stabili assumono la forma di una corona. </p><p>Un'importante caratteristica strutturale degli eteri corona è che il diametro della cavità creata dagli <a href="/wiki/Atomi" class="mw-redirect" title="Atomi">atomi</a> di <a href="/wiki/Ossigeno" title="Ossigeno">ossigeno</a> che si ripetono nel ciclo è paragonabile al diametro degli <a href="/wiki/Ione" title="Ione">ioni</a> di <a href="/wiki/Metalli_alcalini" title="Metalli alcalini">metalli alcalini</a>. La cavità di un etere corona è una regione polare e le coppie di <a href="/wiki/Elettroni" class="mw-redirect" title="Elettroni">elettroni</a> non condivisi degli ossigeni che formano la cavità solvatano efficacemente gli ioni dei metalli alcalini. Da ciò deriva il loro uso in <a href="/wiki/Chimica_organica" title="Chimica organica">chimica organica</a> che permette di ottenere <a href="/wiki/Soluzione_(chimica)" title="Soluzione (chimica)">soluzioni</a> non acquose di composti che altrimenti sarebbero <a href="/wiki/Solubilit%C3%A0" title="Solubilità">insolubili</a> in <a href="/wiki/Solventi_organici" class="mw-redirect" title="Solventi organici">solventi organici</a> apolari o poco polari. In particolare, la dimensione degli ioni metallici chelabili è funzione della dimensione dell'etere ciclico: così, ad esempio, <a href="/w/index.php?title=18-corona-6&action=edit&redlink=1" class="new" title="18-corona-6 (la pagina non esiste)">18-corona-6</a> è in grado di chelare <a href="/wiki/Potassio" title="Potassio">K<sup>+</sup></a>, 15-corona-5 chela <a href="/wiki/Sodio" title="Sodio">Na<sup>+</sup></a> mentre il più piccolo 12-corona-4 riesce a chelare solamente il piccolo ione <a href="/wiki/Litio" title="Litio">Li<sup>+</sup></a>. </p><p>La superficie esterna dell'etere corona è apolare e con caratteristiche di <a href="/wiki/Idrocarburo" class="mw-redirect" title="Idrocarburo">idrocarburo</a>. In conseguenza di ciò, gli eteri corona e i loro <a href="/wiki/Complesso_(chimica)" title="Complesso (chimica)">complessi</a> con gli ioni dei metalli alcalini si sciolgono facilmente in solventi organici non polari. </p><p>Un grosso contributo alla conoscenza della chimica degli eteri corona è stato dato dal <a href="/wiki/Chimica_organica" title="Chimica organica">chimico organico</a> <a href="/wiki/Charles_J._Pedersen" title="Charles J.

Nel secondo numero il numero di atomi di ossigeno (o di altri donatori). Eventuali sostituenti vengono indicati con un prefisso; es. benzo-, dicicloesano-, ecc. Tra i due numeri è interposto il termine corona. Ad esempio il dibenzo[18]corona-6 indica un etere corona sostituito da due gruppi benzo e avente un anello macrociclico di 18 membri, di cui 6 sono atomi di ossigeno donatori. </p><p>Un sistema di nomenclatura più generalizzato per questi leganti organici neutri è stato sviluppato da Vögtle e Weber nel 1979, ma modificato successivamente da Cram nel 1986; in questo sistema qualunque macrociclico, è chiamato corando. Le molecole lineari aperte sono indicate come podandi; sistemi biciclici o oligociclici sono chiamati criptandi; sistemi rigidi basati su frammenti di <a href="/w/index.php?title=%27%27p%27%27-metilanisolo&action=edit&redlink=1" class="new" title="''p''-metilanisolo (la pagina non esiste)">''p''-metilanisolo</a>, sono chiamati sferandi. Tuttavia in generale, per gli eteri corona con donatori all'ossigeno viene mantenuta la vecchia nomenclatura. </p> <table cellpadding="0" cellspacing="5"> <tbody><tr> <td width="120" align="center"><span typeof="mw:File"><a href="/wiki/File:12-crown-4_skeletal.svg" class="mw-file-description" title="Formula chimica di 12-corona-4"><img alt="Formula chimica di 12-corona-4" src="//upload.wikimedia.org/wikipedia/commons/thumb/7/77/12-crown-4_skeletal.svg/80px-12-crown-4_skeletal.svg.png" decoding="async" width="80" height="80" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/77/12-crown-4_skeletal.svg/120px-12-crown-4_skeletal.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/77/12-crown-4_skeletal.svg/160px-12-crown-4_skeletal.svg.png 2x" data-file-width="512" data-file-height="515" /></a></span> </td> <td width="150" align="center"><span typeof="mw:File"><a href="/wiki/File:15-crown-5.svg" class="mw-file-description" title="Formula chimica di 15-corona-5"><img alt="Formula chimica di 15-corona-5" src="//upload.wikimedia.org/wikipedia/commons/thumb/8/88/15-crown-5.svg/110px-15-crown-5.svg.png" decoding="async" width="110" height="105" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/8/88/15-crown-5.svg/165px-15-crown-5.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/8/88/15-crown-5.svg/220px-15-crown-5.svg.png 2x" data-file-width="107" data-file-height="102" /></a></span> </td> <td width="150" align="center"><span typeof="mw:File"><a href="/wiki/File:18-crown-6.svg" class="mw-file-description" title="Formula chimica di 18-corona-6"><img alt="Formula chimica di 18-corona-6" src="//upload.wikimedia.org/wikipedia/commons/thumb/8/89/18-crown-6.svg/120px-18-crown-6.svg.png" decoding="async" width="120" height="115" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/8/89/18-crown-6.svg/180px-18-crown-6.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/8/89/18-crown-6.svg/240px-18-crown-6.svg.png 2x" data-file-width="104" data-file-height="100" /></a></span> </td></tr> <tr> <td align="center">12-corona-4 (1,4,7,10-tetraossaaciclododecano) </td> <td align="center">15-corona-5 (1,4,7,10,13-pentaossaaciclopentadecano) </td> <td align="center">18-corona-6 (1,4,7,10,13,16-esaossaciclottadecano) </td></tr></tbody></table> <div class="mw-heading mw-heading2"><h2 id="Affinità_per_i_cationi"><span id="Affinit.C3.A0_per_i_cationi"></span>Affinità per i cationi</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Eteri_corona&veaction=edit&section=2" title="Modifica la sezione Affinità per i cationi" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Eteri_corona&action=edit&section=2" title="Edit section's source code: Affinità per i cationi"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Gli eteri corona presentano in genere alta affinità per cationi metallici come lo ione potassio.
