The calculated results show: the ground state structures of PtNi5, Pt2Ni4 and Pt3Ni3 clusters are quadrangular bi-pyramid, and Pt4Ni2 and Pt5Ni clusters are triangular bi-pyramid with hat and triangular pyramid with quadrilateral, respectively. From the point of view of thermodynamics, PtnNim clusters are stable because of the negative enthalpy of formation; the positive NICS of PtNi5 clusters show anti-aromaticity, The negative NICS of Pt2Ni4 and Pt5Ni clusters show aromaticity. The number of the IR absorption peak of Pt3Ni3 is the most. The IR and raman absorption peak of PtNi5 , IR of Pt2Ni4, Raman of Pt3Ni3 and Pt4Ni2 have only one. The absorption peak of Pt5Ni appears in the bigger frequencies only, and is zero almost in the small frequencies.
研究结果表明:PtNi5、、Pt2Ni4、Pt3Ni3团簇的基态结构都为四角双锥结构,Pt4Ni2 和Pt5Ni团簇的基态结构分别是戴帽三角双锥和三角锥戴四边形结构;PtnNim团簇的生成焓都为负值,表明团簇在热力学上是稳定的;由NICS值可得,PtNi5团簇具有反芳香性,Pt2Ni4和Pt5Ni团簇具有芳香性;从光谱分析来看,Pt3Ni3团簇的IR较强吸收峰的个数最多,PtNi5团簇的IR和Raman、Pt2Ni4团簇的IR、Pt3Ni3和Pt4Ni2团簇的Raman只有一个强吸收峰值,Pt5Ni团簇的峰值只出现在频率较大的位置,频率小的位置几乎为零。
