摘要: 用量子化学从头算方法研究了C40、Nb@C40+、La@C40+的几何构型和电子结构.C40最稳定构型具有D2对称性.La和Nb原子内含于C40笼中,形成金属夹心碳宪Nb@C40+、La@C40+.C40结合能大于M@C40+(M=Nb,La).

关键词: C40, Nb@C40+, La@C40+, 几何构型, 电子结构

Abstract: The geometric configuration and electronic structure of C40, Nb@C40+ and La@C40+were studied by using quantum chemical ab initio method.The most stable configurat1on of C40 was found to possess D2 symmetry. Nb and La atoms of Nb@C40+ and La@C40+ were insidethe C40 cage, forming endohedral metallofullerenes. Binding energy of C40, was larger thanthose of M@C40+(M=Nb, La).

Key words: C40, Nb@C40+, La@C40+, Geometric configuration, Electronic structure
