Evidence for a novel chemisorption bond: Formate (HCO2) on Cu(100)

  • 1. Corporate Research Science Laboratories, Exxon Research and Engineering Company, Annandale, New Jersey 08801

Description

Surface extended-x-ray-absorption fine-structure measurements reveal that formate (HCO2) groups on Cu(100) chemisorb via the two oxygen atoms in adjacent fourfold hollow sites with an average O-Cu nearest-neighbor bond length of 2.38 +- 0.03 A. This distance is sig- nificantly (approx.0.4 A) longer than typical O-Cu bonds in bulk compounds and all known surface complexes. The unusually large O-Cu distance is attributed to a steric effect involving the C atom in HCO2 and the nearest-neighbor Cu surface atoms
