The chelation of urea (U) with aluminum ion at 90o C were studied by elemental analyses and infrared spectroscopy. The elemental analyses and spectral data were well explained in terms of the formation of AlCl3.U.2CH3OH.H2O(1) and Al2(CO3)3.6H2O (2) complexes. On the basis of the infrared spectral data and the values of stretching vibrational bands of both –C=O and –NH2 groups, the complexes formed between the metal ions and urea were distinguished.
