Supramolecular strategy was employed to achieve the highest nuclearity Co­(II) cluster exhibiting spin-crossover (SCO) behavior. Magnetic susceptibility characterization of the Co4II complex shows that two different spin-transition processes occur. The SCO behavior is directed by the partially deprotonated polydentate ligand, which favors the structural distortion required by the spin transition.
