摘要：

The optimized geometries, infrared spectra and bonding behavior of (XNR)(4) [X = C, Si, Ge, Sn, Pb; R = H, CH3, C(CH3)(3), Si(CH3)(3), C6H5] cubic clusters and their fragments (XNR)(2) were investigated using B3LYP(DFT) method at compact effective potential CEP-121G level for the first time. The results show that the structure of (XNR)(4) is not stable as X = C, the stability of (XNH)(4) is the lowest as R = H. For the same substituent R, the order of stability of cubic clusters is that: (PbNR)(4) > (SnNR)(4) > (GeNR)(4) > (SiNR)(4) > (CNR)(4).
