Abstract
We report the discovery of bridge-bonded methylthiolate, SCH3, along the step edges of the Au(111) surface. Real-space imaging with a scanning tunnelling microscope reveals the presence of bridge-bonded SCH3 along both the [1[1 with combining macron]0] and the [11[2 with combining macron]] oriented...

| Abstract: |
We report the discovery of bridge-bonded methylthiolate, SCH3, along the step edges of the Au(111) surface. Real-space imaging with a scanning tunnelling microscope reveals the presence of bridge-bonded SCH3 along both the [1[1 with combining macron]0] and the [11[2 with combining macron]] oriented step edges. The nearest neighbour distances of SCH3 along these steps are 2a and Image ID:c8cp03684e-t1.gif, respectively. The Au(111) terrace is covered with the usual CH3SAuSCH3 staples. The bridge-bonded alkanethiolate is expected to play a rather significant role in the formation of thiol-passivated Au nanoclusters because of the high fraction of atoms in similar low-coordination sites. |
