Abstract: The density functional theory (DFT) was used to investigate the geometries, electronic structures, and frequencies of CnAl2 (n=1-10) clusters. At B3LYP/6-311G* level, the ground state of CAl2 was a planar structure while other CnAl2 clusters were linear structures with terminal aluminum atom. The energetic analysis showed that CnAl2 clusters with even n were more stable than those with odd n.

Key words: CnAl2 clusters, Ground state structure, Density functional theory, Stability
