摘要: 根据化学键理论与拓朴原理,设计了团簇NinZrn(n=3~5)的可能几何构型,并用从头算方法进行构型优化.结果表明:由NiZr组成的团簇原子间的Zr—Zr和Zr—Ni键明显较强,而Ni—Ni的成键较弱;并发现NinZrn(n=3~5)团簇电子性质与有机烯烃分子等瓣相似,原子之间的成键按照强弱相间的规则分布.

关键词: Ni&mdash, Zr团簇, 从头算, 等瓣相似

Abstract: According to the chemical bond theory and topological principle, 26 clusters NinZrn(n=3—5) have been optimized with quantum chemistry method Gamess. The results indicate that zirconium atoms play an active role in the forming of metallic bonds and the cluster tends to form a planar net structure. We have also found that the electronic structure of NinZrn(n=3—5) planar clusters is a isolobal analogy to alkenes, which show that the strong bonds and the weak bonds are interlaced.

Key words: Ni—Zr clusters, Ab initio, Isolobel analogy
