Abstract

Abstract: The study on the covalence of Be in dimethylberyllium has been undertaken with the method of natural bond orbitals(NBO) on the basis of the new definition of covalence proposed by XU Guang-xian, and the results are reported in this paper.Through the analysis of the eigenvalues and eigenvectors of the submatrices related to proper fragments of the monomer, dimer and polymer of dimethyl-beryllium, it is found that there exists three center-two electron dative bond between the bridge methyl and beryllium atoms whereas there is not dative bond between the terminal methyl and beryllium atom, thus the covalences of Be in monomer, dimer and polymer of dimethylberyllium are 2, 4 and 6 respectively.

Key words: Covalence, Dimethylberyllium, NBO
