By using ab initio method, we have optimized 27 geometric configurations of the 10 valence-electron diberyllium diboride(B2Be2). A singlet tetranhedral like structure h is the most stable one at HF and QCISD(T)/6-311G** level. The stability order of 9 isomers is h>i>g>e>f>c>a>d>b. Further, by means of bond number parameter(BNP), Walsh diagram, energy gap and bond charges, we also revealed bonding properties.
