Descripción
Through Density Functional Theory calculations (with and without long range dispersion corrections) we investigate and compare the stability of a large set of structures involving methanetiol molecularly adsorbed on Au(1 1 1). In particular, we consider possible cooperative effects like the formation of dimers and chains of molecules interacting through SH⋯SH H-bonds. We conclude that structures of dimer H-bonds are the most stable ones for molecular coverages 1/6 ≲θ≤ 1/3. For this range of coverages, a dimer H-bond moiety can act as a precursor for the S-H bond scission process through a cooperative H transfer mechanism.
