摘　　要：研究了４种带ｄｐｐｍ〔二（二苯基膦）甲烷〕桥配体的钯－铑异双金属配合物的ＸＰＳ谱，得到了在配合物生成过程中Ｐｄ、Ｒｈ及Ｃｌ结合能的变化，揭示了它们所处的化学环境，解释了这４种配合物生成过程中所发生的配体迁移、氧化还原及金属－金属成键过程。The X_ray photoelectronspectra (XPS) of four PdRh heterodinuclear complexes with bridged bis(diphenylphosphino)methane (dppm) ligands were studied The changes in electron binding energies of Pd,Rh,and Cl during the formation of the complexes were observed.The results show the effectiveness of XPS for the study of the structure and bonding of PdRh complexes.The migration of the ligands and the redox during the formation of the four Pd_Rh complexes were expounded
