Electrochemistry and Spin‐Crossover Behavior of Fluorinated Terpyridine‐Based Co(II) and Fe(II) Complexes

Due to their ability form stable molecular complexes that have tailor-made properties, terpyridine ligands are of great interest in chemistry and material science. In this regard, we prepared two with different fluorinated phenyl rings on the backbone. The corresponding CoII FeII were synthesized characterized by single-crystal X-ray structural analysis, electrochemistry temperature-dependent SQUID magnetometry. Single crystal diffraction analyses at 100 K these revealed Co–N Fe–N bond lengths typical low spin centers. metal centers coordinated an octahedral fashion backbone twisted out plane unit. investigated cyclic voltammetry UV/Vis-NIR spectroelectrochemistry. All show a reversible oxidation several reduction processes. Temperature dependent magnetometry gradual thermal SCO behavior complexes. EPR spectroscopy was also performed
