complex 3. Even though the systems 1–2 and 3 are quite different,
we observe the formation of a similar framework involving all do-
nor atoms present in L1 and L2. Taking into account that both
dinuclear units in 1 and 2 are linked by two N–C–N bridges, here
the dinuclear moiety 3 is linked by two N–C–C–C–N bridges
(Fig. 6). This compound completes the short list of crystal struc-
tures of nickel dinuclear complexes with N–Cx –N bridges [38].
Interestingly, this bridging configuration imitates rather well the
lateral side of the grid in 1 and 2 (Fig. 3). Bridging ligands L2b
and L2c in 3 are indeed similar than L1a and L1b in 1 except that
the alkoxo group, that was bidentate, becomes monodentate. The
bridge between metal ions is longer in 3 than in 1 and 2
(6.758(3) Å compared to 3.2–3.3 Å – Table 1) because of the methyl
spacer group in L2. The fact that a L2H ligand is found in 3 is rather
interesting taking into account that N-salicylidene aminopyridine
complexes have recently shown to present switchable chromic
properties [39]. This is for instance the case for the mononuclear
complex, [Ni(CH3OH)2(L4H)2(NCS)2] with L4H = N-salicylidene-3-
aminopyridine, that presents weak thermochromism on cooling
below room temperature [39]. The studies of optical properties
of 3, that was beyond the scope of this study, should be considered
in the near future.

7. Concluding remarks
We have described a remarkable asymmetric Cu(II) [2 ꢀ 2] grid-
like complex (1). This tetranuclear unit, which reveals a strong AF
coupling between dinuclear units through a double alkoxo bridge,
is embedded in a sophisticated supramolecular network. Com-
plexes 2 and 4 represent other examples of tetranuclear grids
formed with the same ligand. The use of such Schiff base ligands
thus open perspectives into developing magnetic asymmetric coor-
dination units.
