Abstract: The adsorption of metal-organic complex molecule ([Cu2(μ-O)(dptap)4(NO3)2], where dptap represents 2-(2-pyridylimino)-2H-1,2,4-thia-diazolo[2,3-a] pyridine) on Au(111) surface is studied by STM. STM results show coexistence of undissociative and dissociative adsorption of the molecule. The former shows regular arrangements of the molecule, while the latter gives a (√3×√3)R30°Cu adlayer structure. The possible origin of the coexistence of undissociative and dissociative adsorption is discussed.
