title: A new isomer of C20 and a way to a new C240.
abstract: Here we show that the dynamic simulation of a molecular collision can give insight into new molecular species. In this way, a new stable isomer of C(20) (IV) has been found. It is planar with pentagonal form. This isomer is high in energy compared to the three most stable previously known isomers of C(20): cage (I), bowl (II) and ring (III). Most interestingly, we show that using this new isomer it is possible to construct a macrobucky C(240) (V) that is also stable. The electronic structure of this new isomer of C(240) is very different from properties of the C(240) fullerene. Contrary to the C(240) fullerene, in the new isomer the π electrons are localized.
