Spin crossover cations have been successfully synthesized in the pores of a mesoporous robust Metal–Organic Framework (MOF) MIL-100(Al) through sequential introduction of Fe(III) cations and a sal2trien ligand.
This review discusses the correlation of the local and whole molecular structure of iron(III) complexes with the magnetic properties including the light-induced excited spin-state trapping (LIESST) effect.
The DFT calculations of the spin crossover complex [FeIII(Sal2-trien)]+ with different conformations of ethylene groups were performed. The results explain the presence of disordered structures/transition states of the ethylene groups observed in the [FeIII(Sal2-trien)]+-type structures found in the CCDC database.
Pre- and post-synthetic inclusion of solvent molecules in the anilato-based 2D honeycomb ferrimagnets (NBu4)[MnCr(C6O4Br2)]·G, G = PhCl, PhBr, PhI, PhCH3, PhCN and PhNO2, increases their ordering temperatures (from 5.5–6.3 K to 9.5–11.4 K).
This review covers the incorporation of different magnetic phenomena into MOFs, either in the framework or through the encapsulation of functional species in the pores.
