The results show that the sturcture of each of Tin clusters is obtained by capping one Ti atom to the Tin-1. The Natural bond orbital analysis show that the 4s , 4p, 4d orbitals hybridizes with 3d orbital, and about one electron transfer from 4s orbital to 3d orbital. Moreover, the electrons also transfer between different atom. The results also indicate that the average bond length of clusters were determined by the 4d and 3d orbitals except Ti7. But for Ti7, the average bond length only depend on 3d orbital.

研究结果表明： Tin(n=2~7)团簇都依带帽的形式在前一个团簇的结构基础上加一个原子变化而来；通过自然轨道分析发现，团簇原子的轨道存在sp-d杂化，有大约一个电子从4s转移到了3d，原子之间亦存在电子转移，而且除Ti7外，团簇键长由最外层4d轨道电子和3d轨道共同决定，在Ti7中，团簇键长由3d轨道决定。
