| Outline of Final Research Achievements |
Spin crossover (SCO) complexes have attracted much attention as one of molecular switching materials induced by temperature, pressure, and light.
In order to introduce intermolecular interactions between a cation and anion, multifunctional SCO compounds from the SCO cation and magnetic anion with halogen-bonding interactions were developed. The structural and magnetic characterizations revealed that it was successful to control a paramagnetic-nonmagnetic transformation of the magnetic anion by SCO.
We also discovered completely novel SCO compounds featuring N2O4 and N3O3 donor atom sets which have never been reported. The systematic studies revealed that not isotropic interactions such as Coulomb and dispersion interactions but anisotropic intermolecular interactions such as π-π interactions played a crucial role in the SCO cooperativity which reflects the correlation between the spin-states of the neighboring SCO molecules.
