ABSTRACT
For the rst time, a modied neglect of diatomic overlap (MNDO) study of boron nitride analogs of carbon fullerenes was presented in [1], and B30N30 cage molecule was predicted to be stable and, consequently, possible to be synthesized. Based upon the similarity of structures of BNlayered crystals with graphite, the stable BN nanotubes and hexagonal BN layered into cylinders were assumed. Actually, by means of arc discharge, BN nanosystems had been obtained both from carbon templates [3] and in carbon-free media [4].
