Aluminium complexes of N,N′-ethylenebis(salicylideneimine)(H2salen). X-Ray crystal structures of [{Al(salen)}2(µ-O)]·MeCN and [Al(OC6H2Me3-2,4,6)(salen)]
Abstract
The reaction of AlMe3 with H2salen [N,N′-ethylenenbis(salicylideneimine)] in MeCN gives the five-co-ordinate aluminium complex [AlMe(salen)]1. The interaction of 1 with H2O, HOPh, HOC6H4But-4, HOC6H2Me3-2,4,6, HO2CMe, HO2CPh, acetylacetone and 2-HOC6H4C(O)Me has been studied, and the X-ray structures of two of the products [{Al(salen)}2(µ-O)]·MeCN and [Al(OC6H2Me3-2,4,6)(salen)] have been determined. The proton and 27Al-{1H} NMR and IR spectra of the compounds have been recorded.
