据美国《C&EN》杂志报导,美国宾夕法尼亚州立大学的化学家们宣布,他们发现了一种非常稳定的、具有高度对称性的新分子。这种分子由8个钛原子和12个碳原子构成(Ti_8C_(12)),其对称性可与现在已举世闻名的 C_(60)球状碳分子(富勒苯)相媲美。这些化学家们给 Ti_8C_(12)分子取名为“金属一碳多面苯”(metallo-carbohedrene),或简称为“金属碳分子” (met-car)。同 C_(60)球状碳分子一样,新发现的 Ti_8C_(12)金属碳分子也具有笼形结构,但是,由于这种分子的表面含有过渡金属的原子,因此它的性质很可能与球状碳分子大不相同。 According to the report of C & EN in the United States, chemists at Penn State University announced that they have found a very stable new molecule with a high degree of symmetry. The molecule is composed of eight titanium atoms and twelve carbon atoms (Ti_8C_ (12)). Its symmetry can be compared with the world famous C_ (60) spherical carbon molecule (fullerene). These chemists named the Ti_8C_ (12) molecule as “metallo-carbohedrene,” or simply “met-car.” Like the C 60 spherical carbon molecules, the newly found Ti 8 C 12 metal carbon molecules also have a cage structure. However, since the surface of this molecule contains transition metal atoms, its properties are likely to be related to spherical carbon molecules Very different.
