Abstract
We report the discovery of bridge-bonded
methylthiolate, SCH3 , along the step edges of the Au(111)
surface. Real-space imaging with the scanning tunnelling
microscope reveals the presence of bridge-bonded SCH3
along both the
[1 10]
and the
[112]
oriented step edges.
The nearest neighbour distances of SCH3 along these steps
are 2a and
3a
, respectively. The Au(111) terrace is
covered by the usual CH3SAuSCH3 staples. The bridgebonded
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.
