Heterospin systems have received intense interest in the field
of molecular magnetism.1 Such systems represent one
particularly promising strategy for the design of molecular
magnetic materials such as high TC molecular-based magnets,2
multifunctional materials,3 and single-chain magnets.4 Most
reported heterospin systems so far are constructed from two
different spin carriers such as 3d−3d′,5 3d−4d,6 3d−4f,7 2p−3d,8
and 2p−4f.9 In contrast, very few heterospin compounds
containing three different spin carriers have been obtained
owing to the synthetic challenges inherent in their creation,10 and
only two examples with three different types of spin carriers, 2p−
3d−4f11 and 3p−3d−4f,12 were reported recently. On the other
hand, nitronyl nitroxide radicals can directly bind metal ions not
only to generate heterospin compounds but also to produce the
strongest possible magnetic coupling. Most of nitronyl nitroxide
metal compounds reported to date are based on 3d or 4f metal
ions having zero- and one-dimensional (1D) structure,8a,9 while
the nitronyl nitroxide radical bridged 3d−4f complexes have not
been reported. According to the soft−hard principle, the
lanthanide ions are hard acids; thus, they prefer O rather than
N donor atoms, while 3d metal ions, as borderline acids, have a
strong affinity with N and O donor atoms.13 Thus, in order to
combine 3d and 4f ions within one system, we use a 2-[4-(5-
pyrimidyl)phenyl]-4,4,5,5-tetramethylimidazoline-1-oxyl-3-
oxide (NITPhPyrim) radical ligand containing N and O donor
atoms to build 3d−4f complexes. Noticeably, 3d-rad or 4f-rad
complexes have been obtained by using nitronyl ntroxide radicals
with N donor atoms.14 In this communication, we report on the
synthesis, crystal structure, and magnetic properties of two novel
two-dimensional (2D) compounds, {Ln(hfac)3[Cu-
(hfac)2]3(NITPhPyrim)2} [Ln = Gd (1), Dy (2); hfac =
hexafluoroacetylacetonate], which contain three different types
of spin carriers: a nitronyl nitroxide radical (2p), a 3d metal ion
(Cu2+), and a rare earth ion, 4f (Gd3+or Dy3+). To our
knowledge, they are the first reported 2D 2p−3d−4f compounds
in which a nitronyl nitroxide radical acts as a bridging ligand.
