Abstract: Based on our previous researchwork of closo-hedral cluster (HAlNH)12, the geometries, natural bond orbital, vibrational frequency, energetic parameters, magnetic shielding constants, and nucleus independent chemical shifts of stable endohedral X@(HAlNH)12 complexes (X=Be, Mg, Ca, Zn, Al+, Ga+) were studied at the B3LYP/6-31G(d) level of density functional theory. The transition states (TS) of guest X shifting from the cage center toward a face of six-membered ring were investigated by the QST3 method of Gaussian 03 package and demonstrated with intrinsic reaction coordinate (IRC). It was found that the X@(HAlNH)12 complexes (X=Be,Mg, Zn, Al+, Ga+) were kinetically stable structures, and the complex Ga+@(HAlNH)12 was energetically favorable than the other complexes in thermodynamics.
