文摘The equilibrium geometrical optimizations and frequency calculation on B2N2 molecule in the singlet have been made at B3LYP/6-311+G*and CCSD/6-311+G*levels,respectively.The seven stable equilibrium structures were obtaind. The rhombus D2h structure of BNBN is the most stable and its electronic state is1A.g.
