Three Examples of Nonclassical Fullerenes with Tetrahedral Structure

摘要

Classical fullerenes are molecules consisting of pentagons and hexagons. As a matter of fact, each classical fullerene contains exactly 12 pentagons as a consequence of Euler's Theorem. On the other hand, nonclassical fullerenes contains also, square, heptagonal, or octagonal faces. Several works have considered fullerenes with heptagonal rings; for instance in [1]. Another fields where nonclassical fullerenes appear are shown in [2], [3], [4], [5], and [6].
