A comparison with aluminum(III)\u2212alanine complexes is also presented. The polarizability arising from the ring has been seen to be a key factor in the stability of the complexes, with the order being Trp-AlIII &amp;gt; Tyr-AlIII &amp;gt; Phe-AlIII, starting from the most stable one. Cation\u2212\u03c0 interactions between the metal and the aromatic ring are present in the lowest energy conformers, especially for Trp, which seems to be very well suited for these kinds of interactions, occurring with both the six- and five-membered rings of the indole side chain. The most stable coordination mode for the three AAAs is found to be tricoordinated with the N and O of the backbone chain and the aromatic ring, as was found theoretically and experimentally for other metals.<\/jats:p>","DOI":"10.1021\/ic7004776","type":"journal-article","created":{"date-parts":[[2007,7,3]],"date-time":"2007-07-03T08:00:35Z","timestamp":1183449635000},"page":"6413-6419","source":"Crossref","is-referenced-by-count":11,"title":["Complexation of AlIII by Aromatic Amino Acids in the Gas Phase"],"prefix":"10.1021","volume":"46","author":[{"given":"E.","family":"Rezabal","sequence":"first","affiliation":[{"name":"Kimika Fakultatea, Euskal Herriko Unibertsitatea and Donostia International Physics Center (DIPC), P.K. 1072, 20080 Donostia, Euskadi, Spain, and Dipartimento di Chimica and Centro di Calcolo ad Alte Prestazioni per Elaborazioni Parallele e Distribuite-Centro d'Eccellenza MIUR, Universit\u00e0 della Calabria, I-87030 Arcavacata di Rende (CS), Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Marino","sequence":"additional","affiliation":[{"name":"Kimika Fakultatea, Euskal Herriko Unibertsitatea and Donostia International Physics Center (DIPC), P.K. 1072, 20080 Donostia, Euskadi, Spain, and Dipartimento di Chimica and Centro di Calcolo ad Alte Prestazioni per Elaborazioni Parallele e Distribuite-Centro d'Eccellenza MIUR, Universit\u00e0 della Calabria, I-87030 Arcavacata di Rende (CS), Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
