摘要

Reactions of bis(N-phenylsalicylideneiminato)aluminium(III)di(mu-isopropoxo)di(isopropo xo) aluminium(III), [C6H4O{CH=N(C6H5)}](2)Al(mu-OPri)(2)Al(OPri)(2) (1) with simple and internally functionallized oximes in 1:1 and 1:2 molar ratios in refluxing anhydrous benzene yield binuclear complexes of the type, [C6H4O{CH=N(C6H5)}](2)Al(mu-OPri)(2)Al(ON=CRR')(OPri) and [C6H4O{CH=N(C6H5)}](2)Al(mu-OPri)(2)Al(ON-CRR')(2) [where R=R'=CH3; R=CH3, R=C4H3S-2, C4H3O-2 and C5H4N-2], respectively containing aluminium(III) atoms in six- and four-coordination sites. All these binuclear complexes are characterised by elemental analysis, molecular weight measurements and spectroscopy [IR and NMR(H-1, C-13 and Al-27)]. Reaction of bis(N-phenylsalicylideneiminato)(isopropoxo)aluminium(III) with 2-acetylthiophenyloxime in 1:1 molar ratio in refluxing anhydrous benzene, yields a novel heteroleptic compound, [C6H4O{CH=N(C6H5)}](2)Al{ON=C(CH3)C4H3S-2} (10). The crystal structure of [C6H4O {CH =N(C6H5)}](2)Al {ON =C(CH3)C4H3S-2} . CH2Cl2 shows five-coordination around the aluminium(III) atom. (C) 2003 Elsevier Ltd. All rights reserved. [References: 16]
