Abstract

{New, potentially hexadentate (N3O3) amine phenol ligands (H3IIa = 1,1,1-tris(((2’-hydroxybenzyl)amino)methyl)ethane; H3IIb = 1,1,1-tris(((5’-chloro-2’-hydroxybenzyl)amino)methyl)ethane; H3IIC = 1,1,1-tris(((5’-bromo-2’-hydroxybenzyl)amino)methyl)ethane; H3IId = 1,1,1-tris(((3’,5’-dichloro-2’-hydroxybenzyl)amino)methyl)ethane) have been prepared and characterized by various spectroscopic methods (IR, FAB-MS, NMR). The N3O3 amine phenols are KBH4 reduction products of the corresponding Schiff bases derived from the condensation reactions of 1,1,1-tris(2-aminomethyl)ethane (tame) with 3 equiv of either salicylaldehyde or ring-substituted salicylaldehydes. Neutral binary metal complexes, [M(L)] (M = Al, Ga, In; L = IIa, IIb, IIc, IId) were obtained from the reactions of Al3+, Ga3+, or In3+ With N3O3 amine phenols in the presence of 3 equiv of a base (acetate or hydroxide). The molecular structures of [AI(IIc)]4[Na(H2O)]2)(ClO4)2.6.2H2O, [Ga(IIa)].4.4H2O, and [In(IIa)].4.6H2O were determined by X-ray methods. Crystals of [Al(IIc)]4[Na(H2O)]2(ClO4)2.6.2H2O are orthorhombic, Pbcn
