Abstract

{The coordination chemistry of Ga(III) and Al(III) with 2-(2’-hydroxyphenyl)-2-benzoxazole (Hhbo) was investigated both in the solid state (X-ray crystallography) and in solution (H-1, C-13, Al-27 N MR) These two group 13 metal ions exhibit different reactivities toward this bulky bidentate ligand leading with Ga(III) to the formation of Ga(hbo)3 (1) and [Ga(hbo)2(0,0’-CH3CO2)] (2) complexes depending on the reaction conditions. With AI(III), the only complex formed is[Al(mu-OH)(hbo)2]2(3). The Ga bis(ligand) acetate complex 2 (C28H19GaN2O6) crystallizes in the monoclinic space group C2/c with a = 16.008(3) angstrom
