surface.
warmly thank Amable Bernabꢁe (ICMAB-CSIC) for recording IR
and LDI-TOF spectra. We acknowledge the ESRF for the provision
of beamtime, and we are grateful to J.C. Cezar (ESRF) for his
precious assistance in using beamline ID8.

Unlike the previously described Fe4 on gold,43 it is important
to notice that here the terbium complexes are not wired
covalently to the surface by a long alkyl chain but are on the
contrary lying directly on top of the graphite surface. In principle,

destroyed the SMM properties, but the XMCD magnetization
hysteresis measurements showed that this is not the case and,
therefore, that this assembly procedure is an interesting one for
the preparation of SMM arrays.

Two very recent contributions present the magnetic behavior
of nonsubstituted double-decker complexes on Au(111) and
Cu(100),9,13 showing that TbPc2 does not present any hysteresis
of magnetization when deposited on Cu(100), while on Au(111)
it is clearly observed. It is worth noting the presence of an open
butterfly hysteresis both in thick and thin layers of TbPc2 on
Au(111). The latter shows a narrower hysteresis than the former
one; a result which is consistent with those presented here.
To the best of our knowledge, it is the first time that
magnetization hysteresis is observed for molecules of a double-
decker phthalocyanine lanthanide complex that are all in intimate
contact with a graphite surface. Importantly, the slow magnetic
relaxation rate, characteristic of these compounds is still present in a
i
well-characterized submonolayer sample of the neutral Pc Tb
complex, and the behavior of the sample is not very different from
the bulk complex measured in the same conditions.
