Organometallic sandwich complexes exhibit a number of potential structural and electronic properties and attract the attention of many researchers in recent years. In this paper, we systematically studied the structure and stability of Ln(C8H8)‾ and Ln(C8H8)2‾ (Ln = Ce, Eu, Ho, Nd and Yb) complexes using density functional theory calculations. It is found that the Ln (C8H8)‾ (Ln = Ce, Eu, Ho, Nd and Yb) complexes have high C8v point symmetry structure and Ln(C8H8)2‾ are typical "sandwich" structure. The stability of Ln(C8H8)‾ and Ln(C8H8)2‾ is explained by the calculation of binding energy and HOMO-LUMO gap. The study of binding energy shows Eu(C8H8)‾, Eu(C8H8)2‾, Ho(C8H8)‾ and Ho(C8H8)2‾ have significantly high binding energy and exhibit high thermodynamic stability. The HOMO-LUMO gaps of Ho(C8H8)‾, Eu(C8H8)2‾ and Ho(C8H8)2‾ are 2.016, 3.117 and 3.098 eV, respectively, which are obviously higher than other complexes. The result implies that these three complexes are more stable than other complexes. Besides, the comparison of experimental and theoretical vertical electron detachment energy (VDE) of Ln(C8H8)2‾ is presented in this paper. The relative error (between theoretical and experimental) of vertical electron detachment energies of sandwich complexes Ln(C8H8)2‾ is in the range of 3.7-9.3%, indicating that the theoretical and experimental results are in good agreement.
