Ab initio study of electronic structures of Ptn clusters (n = 2–12)

Electronic structures of a series of Pt_n clusters (n = 2–12) have been calculated by ab initio method (SCF/MP2). The result shows that compared to that at the saturated coordination site, Pt at the unsaturated coordination site has lower Pt₆₅ electron occupancies, and the relationship between the electronic structure and the cluster size has been discussed. It is found that when the number of Pt in cluster reaches 7, electronic structures become more like the metallic ones. © 1997 John Wiley & Sons, Inc. Int J Quant Chem 62 : 427–436, 1997
