Simultaneous magneto-dielectric transitions in a fluorescent Hofmann-type coordination polymer

Abstract

The design of magnetic molecular materials exhibiting multiple functions has garnered significant interest owing to their potential applications in molecular switches, sensors, and data storage devices. In this study, we...

Rotational order–disorder and spin crossover behaviour in a neutral iron(ii) complex based on asymmetrically substituted large planar ionogenic ligand

“…The SCO behaviour is associated with dramatic changes in the magnetic, optical and dielectric properties of the material. 4 Furthermore, the transfer of electrons between the e g and t 2g orbitals is accompanied by remarkable changes in the Fe II –ligand bond lengths (about 0.2 Å on average for Fe II –N bonds) and angles. In the solid state, these structural changes are propagated throughout the crystal by elastic interactions.…”
