Abstract: The geometry of hexanitrohexaazaisowurtzitane(CL-20) is optimized at the B3LYP/631G** level. The population, natural bond orbital and vibrational frequency analyses are carried out. Apossible stable molecular geometry is obtained, which is in agreement with the experimental results. The relationship between the bonding behavior and the properties of CL-20 has been discussed.

Key words: Hexanitrohexaazaisowurtzitane(CL-20), B3LYP, Energetic material, NBO
