Abstract: The silylenoid H2SiClBeCl was studied using DFT B3LYP and QCISD methods. Geometry optimization calculations indicated that H2SiClBeCl had three equilibrium configurations, in which the tetrahedral structure was the lowest in energy and was the most stable structure. The transition states for isomerization reactions of H2SiClBeCl were located and the energy barriers were calculated. For the most stable one, the infrared spectrumhad been simulated.

Key words: Silylenoid H2SiClBeCl, B3LYP, QCISD, Isomerization
