Reactions of Aluminium isopropoxide with monofunctional bidentateSchiffbases, such as salicylidene-o-toluidine, salicylidene-p-toluidine, 2-hydroxy-1-naphthylmethylidene-p-toluidine and 2-hydroxy-1-naphthylmethylidene-p-toluidine in different stoichiometric ratios have yielded products of the type Al(OPri)2(SB), Al(OPri)(SB)2, and Al(SB)3(whereSB−is the anion of the correspondingSchiffbase,SBH). Bifunctional tetradentateSchiffbases in 1∶1 and 2∶3 molar ratios Al(OPri)3:SBH2 yielded insoluble derivatives of the type Al(OPri)SBand Al2(SB)3(whereSB−represents the anion of theSchiffbaseSBH2andSBH2=bis-salicylaldehyde-o-phenylene-diamine or bis-salicylaldehyde-p-phenylenediamine). The newSchiffbase derivatives have been characterized by elemental analyses, infrared spectroscopy and molecular weight determi
