It is shown by scanning tunnelling microscopy (STM) that the
surface can be used as a template to form other
nanostructures after it has restructured upon exposure to
hydrogen. Extremely long and defect-free nanowires
produced in the restructuring process can be decorated by,
e.g., so that FeIrFe nanochains develop as sandwiches of
atomically thin and wires. Laterally they
recur with 1.36
periodicity on average, i.e. two
atomic rows are missing between two sandwiches. By additional
deposition of this space can be filled so that the
vacancy spaced {
} lateral superlattice transforms
to a {
} superlattice. Their crystallography is
determined by quantitative low-energy electron diffraction (LEED).
