Based on the analysis of the Jahn-Teller effect, vibronic interaction and the resolution of group representations, the possible geometrical configurations of 〓 have been derived for the first time. The Gaussian-98 program has been used to optimize the geometrical configurations of 〓 based on B3LYP/6-311G method. It is found that there are at least six different stable geometrical configurations for 〓 The results show that the multiplicity of 2S＋1=7 for cluster 〓 is the most stable state among the eight geometry configurations.
