The aluminum alkylsalicylate six-nuclear complex having nine-ligands obtained from an alkylsalicylate and six aluminum atoms as nuclear components, is characterized in that the six-nuclear complex comprises two aluminum alkylsalicylate tridentate complexes each having three ligands obtained from a tridentate alkylsalicylate and three aluminum atoms as nuclear components, and that ligands obtained from at least bidentate alkylsalicylate and ligands obtained from hydroxyl anions are arranged on aluminum atoms to crosslink the two three-nuclear complexes.
