Supramolecular Modulation of Spin Crossover in an Fe(II) Dinuclear Triple Helicate

A spin-crossover (SCO) active dinuclear Fe(II) triple helicate of the form [Fe2L3](4+) was combined with additional supra-molecular components in order to manipulate the interhelical separation and steric congestion and to study the magneto-structural effects on the ensuing composite materials. A more separated array of SCO units produced more extensive spin-transitions, while a tightly arranged lattice environment stabilized the low-spin state. This study highlights the important interplay between crystal packing, intermolecualr interactions, and the magentic behavior of SCO materials.

This study investigates the interaction between crystal packing, intermolecular interactions, and the magnetic behavior of SCO materials. The research found that a more separated array of SCO units leads to more extensive spin-transitions, while a tightly arranged lattice environment stabilizes the low-spin state.
