Using B3LYP/6-31G* to optimize (XY)12 (X=B, Al; Y=P) clusters, the geometries with the lowest energy were achieved. The geometries, energy gap of HOMO-LUMO, the heats of formation, nucleus independent chemical shifts (NICS) and free energy were discussed at the same time. The calculations predict the existence of pentagon in cage besides rhombus and hexagon. The most stable structure is in Th symmetry with six isolated four-membered rings.

Key words: (BP)12 and (AlP)12 cluster, structure and stability, NICS, free energy
