Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): НАНОТРУБКИ БОР-АЗОТНЫЕ -- КВАНТОВО-ХИМИЧЕСКОЕ МОДЕЛИРОВАНИЕ Аннотация: A quantum-chemical model was made of new quasi-one-dimensional crystals, consisting of regular chains of metallocarbohedrenes Sc8C12, Ti8C12, and V8C12 (isomers with Th symmetry) inside a single-wall (12,0) boron-nitrogen nanotube. Their electronic characteristics, the nature of the interatomic bonds, and the relative stability in relation to the electronic concentration in the (Sc8C12@(12,0)BN-NT ® Ti8C12@(12,0)BN-NT ® V8C12@(12,0)BN-NT) systems and the mutual arrangement of the metallocarbohedrenes and the nanotube are discussed Полный текст |
