Abstract
A novel heterocyclic derivative of aluminium(III) [C6H4O{CH=N(C6H5)}](2)Al(µ-OPri)2 Al(OPri)(2) 1 has been synthesized by the reaction of aluminium isopropoxide with N-phenylsalicylidene imine in 1: 1 molar ratio in refluxing anhydrous benzene. Reactions of 1 with alkoxyalkanols in 1:1 and 1:2 molar ratios in refluxing anhydrous benzene yielded binuclear complexes of the types, [C6H4O{CH=N(C6H5)}](2)Al(µ-OPri)(2)Al(OCH2CH2OR)(OPri) and [C6H4O{CH=N(C6H5)}](2)Al(µ-OPri)(2)Al(OCH2CH2OR)(2) (where R=CH3, C2H5 and C4H9n), respectively. All of these binuclear complexes have been characterized by elemental analysis, molecular weight measurements, and spectral studies. The FAB mass spectrum and Al-27 NMR spectrum of 1 indicate that it is a discrete unsymmetrical dimer containing four- and six-coordinated aluminium(III) atoms as confirmed by its single crystal X-ray structure.
