超分子策略，以实现最高的核Co（II）簇表现出自旋交叉（SCO）的行为。磁化率的Co4（II）复杂的表征表明，两个不同的自旋跃迁过程发生。SCO的行为是由部分去质子化的多齿配体，这有利于自旋跃迁所需的结构畸变。
Supramolecular strategy was employed to achieve the highest nuclearity Co(II) cluster exhibiting spin-crossover (SCO) behavior. Magnetic susceptibility characterization of the Co4(II) 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.
