Iron complexes of bridging azo ligands in aqueous solution: changes in the thermal switching mechanism on coordination and oxidation state of metal centres

Abstract

TThe three azobenzenes CN(C6H4)-N=N-(C5H4N) (py-iso), CN(C6H4)-N=N-(C6H4)CN (cyano-iso) and CN(C6H4)-N=N-(C6H4)NC (iso-iso) with good coordinating groups (pyridine, phenylcyano or phenylisocyano) at the ends of the diazenyl unit have been synthesized and fully...
