A method for evaluating the energy stability of carbon nanoclusters is prop
osed. The stabilities of the nanoclusters with different structures, such a
s diamond and graphite, tubulenes and graphite, are compared. Two series of
stable clusters with new structures, namely, alm-ene and alm-ine, are deri
ved. A comparison is performed for small graphite clusters containing boron
atoms that play a significant role in the reaction of fullerene formation.
