A new Al(III)-organophosphate species was synthesized in aqueous solution at the optimum pH 4. The reacted organophosphate ligand is N-(phosphonomethyl)iminodiacetic acid. The isolated crystalline material was characterized by elemental analysis, spectroscopic techniques (FT-IR, NMR) and X-ray crystallography. The new species contain aluminum ions in an octahedral environment.
