• We perforun microscopic total-eraergy calctrlations based on a transferable tight-binding modelcombined xvith conjugate-gradient raainiunization technique for various zntrltivacancies V. in 81.We find that stable natrltivacarucies (magic nurnbers of negative 81 clusters) are V5, VIO, V14, V17,V22, V26 and V35. We also find that both topological networks of vacant sites and relaxation ofsurrotrnding atotaas are crtrcial to deternaine energetics of the untrltivacancies,
