Spin-crossover (SCO) compounds are fascinating switchable
materials with great potential for the development of novel
technological devices. These coordination complexes exhibit
metal ions with two possible electronic configurations (low-
spin, LS, and high-spin, HS) which can be toggled using exter-
nal stimuli such as temperature, pressure, or light
irradiation. The different magnetic, optical, and structural
features of the two states allow these materials to be exploited
for a wide range of applications, such as sensors, actuators, 
or for information storage. Interestingly, the physical pro-
perties of SCO compounds can be tuned by modifying the
weak non-covalent interactions exhibited within or in between
their molecular entities. In host–guest systems, these inter-
actions offer a versatile tool, for example, for manipulating the
transition temperature of encapsulating SCO complexes simply
by altering the nature of the supramolecular guest, as shown
in dinuclear helicates, tetrahedral cages, or cubic architec-
tures. Long range intermolecular interactions can be
exploited as well to tune or even to activate/deactivate the SCO
behaviour. Such modulation arises from the nature and
strength of such interaction, which influence the communi-
cation between molecules and thus its cooperativity, or
affect the ligand field exerted by the donor set and therefore
the SCO temperature.
