Herein we present co-crystallization as a strategy for materials discovery in the field of switchable spin crossover (SCO) systems. Using [Fe(3-bpp)2]·2A (where 3-bpp = 2,6-bis(pyrazol-3-yl)pyridine, A = BF4-/PF6-) as a starting point, a total of 11 new cocrystals have been synthesized with five different dipyridyl coformers. Eight of these systems show spin crossover behavior, and all show dramatically different switching properties from the parent complex. The cocrystals have been studied by variable temperature single-crystal X-ray diffraction and SQUID magnetometry to develop structure-property relationships. The supramol. architecture of the cocrystals depends on the properties of the coformer. With linear, rigid coformer mols. leading to 1D supramol. hydrogen-bonded chains, while flexible coformers form 2D sheets and bent coformers yield 3D network structures. The SCO behavior of the cocrystals can be modified through changing the coformer and thus co-crystallization presents a rapid, facile and highly modular tool for the discovery of new switchable materials. The wider applicability of this strategy to the design of hybrid multifunctional materials is also discussed.
