Heterobimetallic lithium–iron coordination compounds are interesting targets for several reasons: they can be used as precursors for mixed metal oxides, as catalysts, for example, for ring-opening polymerization reactions or to study oxidation/reduction processes. Finally their magnetic properties are also of interest. New heterobimetallic aryloxide complexes, namely...

Inducing spin crossover in amphiphilic iron(III) complexes

Thermal spin crossover (SCO) was induced in a high-spin FeIII complex by alkylation of the polyamino ligand backbone. The SCO profile was responsive to chain length with partial crossover observed with C₆ alkylation and full transition upon lengthening to C₁₂. No crossover was observed when the backbone was unfunctionalised, and all three complexes were obtained as unsolvated...
