Abstract
We have combined photoelectron diffraction in both scanned-angle and s canned-energy modes with Hartree-Fock calculations to investigate the interface structure of HCOO- on TiO2(110). Formate anions bind through the oxygens to Ti cation rows along [001] with a 2 X periodicity and an O-C-O bond angle of 126 +/- 4 degrees. Each anion binds to two Ti c ations with an adsorbate-substrate bond distance of 2.0 +/- 0.1 Angstr om.
