Self-assembly of a supramolecular spin-crossover tetrahedron

Abstract

A new mononuclear iron(ii) SCO compound featuring H-bonding donor and acceptor units has been synthesized and exploited to produce a purely supramolecular switchable [Fe4] tetrahedron. Magnetic and crystallographic measurements evidence a singular magnetic behavior for each of the four Fe(ii) centers of the generated architecture and underscore the potential of this strategy to develop novel SCO materials.
