The density functional calculation with the generalized gradient approximation is applied to study the structural, properties of AlnGan clusters up to n=12. At the same time the frequency was performed when the structure optimization in order to assure the calculated-ground states were real low-lying. The nearest-neighbor distance, total energy, electron affinities and HOMO-LUMO gap were presented and discussed to prove the calculations. Some magic clusters in neutral, cationic, and anionic form compared to its neighboring clusters are argued according to the calculated results of the second energy difference and electronic properties.
