ABSTRACT: The title compound, [Al(CH(3))(2)(C(25)H(21)N(2)O)(C(4)H(8)O)], was isolated as a minor component from a reaction mixture of the parent indolyl ligand and trimethyl-aluminum in tetra-hydro-furan. The ligands adopt a distorted tetra-hedral geometry around aluminium. Obvious hydrogen-bonding interactions are not present.
