A tensor LEED study of an unusual cyclic hydrocarbon intermediate formed by benzene adsorption on Co(10 1̄ 0)

Tensor LEED has been used to determine the geometry of a p(3×1) phase formed by benzene adsorption to saturation coverage on Co(10 1̄ 0) at 300 K. In contrast to benzene overlayers previously subjected to quantitative surface structural analysis, adsorption occurs with the ring in a tilted geometry across the substrate close packed [12 1̄ 0] atomic rows in an off-centre bridge site with Cs symmetry.
