Abstract

A variable-low-temperature scanning tunneling microscope (STM) was used to observe oxygen (O ₂), ethylene (C ₂H ₄), and acetylene (C ₂H ₂) molecules on a Ag(110) surface and the various complexes that were formed between these two hydrocarbons and oxygen at 13 K. Ethylene molecule(s) were moved to the vicinity of O ₂ either by STM tunneling electrons at 13 K or thermally at 45 K to form (C ₂H ₄) _x-O ₂ (x = 1-4) complexes stabilized by C-H⋯O hydrogen bonding. Acetylene-oxygen complexes involving one or two acetylene molecules were observed.
