Abstract:

The Localized molecular orbitals of element clusters Li~e_n(n=1-6, 8; e=+1) have been calculated. The results show besides the two-centre bonds, a variety of many center bonds including closed-form and open-form ealst in Li~e_n. The many-centre bonds and the coordination numer as a character of metallic bonds increase with the increasing of the size of clusters. The influences of the geometric structures and electronic states on the bonding have been discussed.

Key words: Localized molecular orbitals, Lien elemental clusters, Many-centre bonds
